Preserving The Garden Harvest: Instructions For Freezing Food

Freezing food for preservation is a method that has been practiced for centuries, although the widespread use of home freezers is a more recent development. Before the invention of mechanical refrigeration, people used natural methods to freeze and preserve food. In colder regions, they took advantage of winter temperatures by storing food in ice houses or caves. Ice was collected during the winter and used to create insulated storage areas where food could be kept frozen.

The introduction of home refrigerators with freezer compartments in the 1930s and 1940s made freezing food more accessible to households. These early freezers were smaller in size compared to today's models but provided a convenient way to preserve food at home. As technology improved, home freezers became larger and more efficient, enabling people to store a wider variety of foods for longer periods.

Today, freezing is one of the most common methods of food preservation. It allows for the long-term storage of a wide range of foods while retaining their nutritional value, flavor, and texture. Freezing food at home has become a routine practice for many households, providing them with the convenience of having a variety of preserved foods readily available throughout the year.

Is freezing food safe?

Yes, freezing food is generally considered safe when done properly. Freezing slows down the growth of microorganisms, such as bacteria and molds, which can cause food spoilage and foodborne illnesses. It helps to preserve the quality, nutritional value, and taste of many foods.

However, it's important to follow proper freezing practices to ensure safety:

Keep your freezer at or below 0°F (-18°C) to ensure food stays frozen. Use a freezer thermometer to monitor the temperature regularly. Proper packaging is crucial to prevent freezer burn and maintain the quality of frozen food. Use moisture-proof, airtight containers or freezer bags designed for freezing. Remove excess air from the packaging to minimize freezer burn.

Label packages with the name of the food and the date it was frozen to help keep track of the contents and use them within the recommended time frame.

To maintain the best quality, use the "first in, first out" principle. Consume the oldest frozen items first and avoid storing frozen food for excessively long periods. Place newer items behind items that have already been frozen to make it easier to remember which produce needs to be used first.

It's important to note that while freezing can prevent the growth of bacteria, it does not kill bacteria that may have been present in the food before freezing. Therefore, it's crucial to handle and prepare foods properly before freezing to minimize the risk of foodborne illnesses. Additionally, some foods may experience changes in texture or flavor after freezing, so it's important to consider the suitability of certain foods for freezing. If you have any doubts about the safety or quality of a specific food item, it's always best to consult reliable sources or food safety experts for guidance.

Is freezer burn bad for you?

Freezer burn itself is not considered unhealthy or harmful to consume. It refers to the dehydration and oxidation of the food's surface when it is exposed to air inside the freezer. While freezer burn may cause changes in texture, flavor, and appearance, it does not pose a risk to food safety.

However, consuming freezer-burned food may result in a less desirable eating experience. The affected areas of the food can become dry, discolored, and develop a slightly off taste. It's always recommended to trim off the freezer-burned portions before consuming the remaining parts of the food.

How long will frozen foods last?

The storage time for frozen produce can vary depending on the specific type of produce, the quality at the time of freezing, and the storage conditions. Generally, frozen produce can maintain its quality and be safe to eat for an extended period if stored properly.

Fruits: Most fruits can be stored in the freezer for 8 to 12 months. However, citrus fruits may have a shorter storage time of around 4 to 6 months.

Vegetables: Vegetables can typically be stored in the freezer for 8 to 12 months. Some vegetables with higher water content, such as leafy greens, may have a shorter storage time of around 3 to 6 months.

Berries: Berries, such as strawberries, blueberries, and raspberries, can be stored for 8 to 12 months.

Techniques for freezing food

Freezer Bags or Containers: Transfer the food into freezer-safe bags or containers such as silicone bags or mason jars. Remove excess air from the bags before sealing them to minimize freezer burn.

Tray Freezing: This method is useful for freezing individual items, or small pieces of food that you don’t want getting stuck together. Place the food in a single layer on a tray and put it in the freezer. Once the food is frozen, transfer it to freezer bags or containers for long-term storage.

Vacuum Sealing: Vacuum sealers remove air from the packaging, creating an airtight seal around the food. This method helps to prevent freezer burn and extends the shelf life of frozen food. This is my preferred method for storing frozen food, especially produce we harvest from our garden.

Freezer Paper: Wrap the food tightly in freezer paper, aluminum foil, or plastic wrap. Make sure to label and date the package. This method is suitable for foods with minimal moisture, such as meats or baked goods.

Ice Cube Trays: Ideal for freezing small portions, such as herbs, sauces, or baby food. Pour the liquid or puree into the compartments of an ice cube tray and freeze. Once frozen, transfer the cubes to a freezer bag for storage.

Blanching and Flash Freezing: Some vegetables benefit from blanching before freezing to maintain their texture and color. Briefly blanch the vegetables in boiling water, then plunge them into ice water to stop the cooking process. Drain well, pack into freezer bags or containers, and freeze. Vegetables that benefit the most from blanching include green beans, broccoli, carrots, brussels sprouts, peas, corn, cauliflower, asparagus and spinach.

How to Thaw Frozen Produce

The safest method for thawing frozen produce is to transfer it from the freezer to the refrigerator. This slow thawing process allows the produce to gradually reach a safe temperature without compromising its texture or flavor. Remember to place the frozen package in a leak-proof container or on a plate to catch any potential drips.

If you need to thaw produce more quickly, you can use the cold water thawing method. Place the frozen package in a sealed plastic bag and submerge it in cold water. Change the water every 30 minutes to ensure it stays cold. Note that this method should be used for immediate use of the thawed produce.

Thawed vegetables like peas, carrots, and corn are excellent additions to soups, stews, and sauces. They bring vibrant colors, flavors, and nutrients to your dishes. Thawed fruits like berries, peaches, or rhubarb can be used in baking recipes, such as pies, cobblers, or muffins. For best results, drain excess liquid from the thawed fruits before using them in recipes. Thawed vegetables, such as green beans, broccoli, or cauliflower, can be blanched quickly to revive their vibrant colors and crispness. Use them in salads or as side dishes, either raw or lightly steamed, for added freshness and nutrition. Remember that the texture of thawed produce may differ slightly from fresh produce, but the flavor and nutrients are still present.

Troubleshooting Issues With Freezing Produce

Freezer burn can occur when frozen produce is exposed to air, leading to dehydration and a change in texture and flavor. To prevent freezer burn, make sure to store your produce in airtight containers or freezer bags, removing as much air as possible. Additionally, consider using vacuum-sealed bags for optimal protection. If you notice signs of freezer burn on your produce, simply trim off the affected areas before using them in recipes.

Some vegetables may experience changes in texture after freezing. For example, leafy greens like spinach or lettuce may become wilted or lose their crispness. In these cases, it's best to use them in cooked dishes rather than raw salads. Similarly, root vegetables such as potatoes or carrots may become slightly softer after freezing. They are still safe to consume and can be used in mashed dishes, soups, or stews. Blanching helps preserve the color, texture, and flavor of the vegetables, as well as helps to deactivate enzymes that can cause deterioration during storage. It's recommended to blanch most vegetables before freezing unless they are intended for cooking in recipes where texture changes are not a concern.

Some fruits, especially those with delicate textures, benefit from being frozen in a syrup to maintain their quality. The syrup helps retain moisture and prevents the fruit from becoming mushy. Use a light sugar syrup (made by dissolving sugar in water) or a simple fruit juice syrup. The specific syrup concentration can vary depending on personal preference and the sweetness of the fruit.

Can you refreeze thawed produce?

It's generally recommended to avoid thawing and refreezing produce repeatedly, as it can lead to a loss of quality and potential food safety issues. If you have a large quantity of frozen produce and only need a portion, it's best to thaw and use what you need while keeping the rest frozen.

Freezing is an accessible method of food preservation for just about anyone, and is especially useful during summer harvest season when it can be difficult to keep up with all the produce coming in from the garden. You can even freeze tomatoes whole to process into sauce and can at a later date. Freezing also provides easy access to quick meals for nights when you aren’t able to cook, and prevents food waste.

Pickled cauliflower florets are not only visually appealing but also provide a tasty and tangy addition to salads, antipasto platters, or relish trays.

How to pickle food

Start by selecting fresh and high-quality vegetables or fruits for pickling. Wash them thoroughly and trim off any unwanted parts. Cut the produce into desired shapes, such as slices, spears, or whole.

In a non-reactive pot, combine vinegar, water, and salt. The ratio of vinegar to water can vary depending on personal preference and the recipe you're using. Generally, a 1:1 ratio of vinegar to water is common. Add salt to taste, and you can also incorporate other flavorings like sugar, spices, or herbs.

Place the pot on the stove and heat the brine mixture until it comes to a boil. Stir occasionally to ensure that the salt is dissolved and the flavors are well combined.

Meanwhile, sterilize glass jars and their lids by boiling them in water for a few minutes or running them through a dishwasher. Once sterilized, pack the prepared vegetables or fruits tightly into the jars, leaving a little space at the top.

At this stage, you can add extra flavorings to the jars, such as garlic cloves, dill sprigs, peppercorns, or chili flakes. These will infuse additional flavors into the pickled food.

Carefully pour the hot brine into the jars, making sure to completely cover the vegetables or fruits. Leave about a 1/2-inch headspace at the top of each jar. If needed, use a clean utensil, such as a chopstick, to release air bubbles and ensure the brine fills all the gaps.

Wipe the jar rims with a clean cloth to remove any spills or brine residue. Place the lids on the jars and tighten them securely. Allow the jars to cool at room temperature. As they cool, you may hear the satisfying "pop" sound indicating a proper seal. Once cooled, store the pickled jars in a cool, dark place like a pantry or cellar. The flavors will continue to develop over time.

Pickled foods need time to develop their flavors. Most pickles are ready to eat after a few days, but the flavors will intensify and improve over several weeks. Keep in mind that some pickles may require longer fermentation periods.

The difference between pickled and fermented food

Pickling is a process of preserving food by immersing it in a brine or vinegar solution. The food is typically cooked or blanched before being submerged in the pickling liquid. Fermentation, on the other hand, is a natural process that occurs when beneficial bacteria, yeasts, or molds break down the sugars or carbohydrates in the food, converting them into acids or alcohol.

Pickling preserves food through the use of acid, typically vinegar, which creates an acidic environment that inhibits the growth of spoilage-causing bacteria. The high acidity of the pickling solution helps preserve the food's texture, color, and flavor. Fermentation, on the other hand, preserves food through the action of beneficial microorganisms. These microorganisms produce lactic acid or alcohol as byproducts, creating an environment that prevents the growth of harmful bacteria.

Pickled foods have a distinct tangy or sour flavor due to the vinegar or acidic brine they are soaked in. The texture of pickled foods can vary depending on the specific food being pickled, but they tend to retain some crunchiness. Fermented foods often have a complex, tangy, or slightly acidic flavor profile. The fermentation process can also introduce unique flavors and aromas. The texture of fermented foods can range from crisp to soft, and they may develop a slightly "fizzy" or effervescent quality.

Pickled foods have a relatively long shelf life due to the high acidity of the pickling solution, which inhibits the growth of spoilage-causing bacteria. They can be stored for several months or even years when properly sealed and stored in a cool, dark place. Fermented foods also have a good shelf life, but the duration may vary depending on the specific food and the fermentation process. Some fermented foods, such as sauerkraut or kimchi, can be stored for several months in the refrigerator or even longer if kept in a cool environment.

Both pickled and fermented foods can offer health benefits. Pickled foods, especially those made with fermented pickling methods like lacto-fermentation, can contain beneficial probiotics that support gut health. Fermented foods are known for their rich content of beneficial bacteria, enzymes, and other compounds that can aid digestion, enhance nutrient absorption, and support overall gut health.

If you’re feeling thirsty, fermented beverages include kombucha (fermented tea), water kefir, milk kefir, traditional fermented beers, and of course wines. Even your sourdough starter is technically a fermented food!

Ways to ferment food

There are countless methods for fermenting foods, depending on the type of food to be fermented. Here are just a few of the more common methods of fermentation:

Vegetable Fermentation: This method involves submerging vegetables in a brine solution or using the vegetables' own juices to create an anaerobic environment. Examples include making sauerkraut, kimchi, and pickles.

Lacto-Fermentation: Lacto-fermentation is a process that relies on beneficial bacteria, specifically Lactobacillus, to convert sugars into lactic acid. It is commonly used for fermenting vegetables, such as cabbage for sauerkraut, or making lacto-fermented beverages like kefir.

Wild Fermentation: This method involves allowing naturally occurring microbes present on the food or in the environment to initiate the fermentation process. Examples include using wild yeasts for sourdough bread or fermenting fruits for natural wines.

Vinegar Fermentation: Fermentation can also be used to make vinegar. This process involves converting ethanol into acetic acid using acetobacter bacteria. It can be done with fruits, grains, or alcoholic beverages.

Dairy Fermentation: Fermentation is used to make various dairy products such as yogurt, kefir, sour cream, and cheese. Bacteria cultures are added to milk, which then ferment and transform the milk into these different products.

Alcohol Fermentation: Fermentation is widely used in the production of alcoholic beverages such as beer, wine, and cider. Yeast is added to sugars, which then convert the sugars into alcohol and carbon dioxide.

What is the difference between pickled and fermented?

Pickling is a process of preserving food by immersing it in a brine or vinegar solution. The food is typically cooked or blanched before being submerged in the pickling liquid. Fermentation, on the other hand, is a natural process that occurs when beneficial bacteria, yeasts, or molds break down the sugars or carbohydrates in the food, converting them into acids or alcohol.

Pickling preserves food through the use of acid, typically vinegar, which creates an acidic environment that inhibits the growth of spoilage-causing bacteria. The high acidity of the pickling solution helps preserve the food's texture, color, and flavor. Fermentation, on the other hand, preserves food through the action of beneficial microorganisms.

Troubleshooting issues with fermented food

Fermenting food at home can be a rewarding process, but occasionally, issues may arise. Mold growth on the surface of fermented food is a common issue. If you notice mold, it's essential to discard the entire batch to avoid any potential health risks. To prevent mold growth, make sure to maintain proper hygiene by sterilizing utensils, containers, and your hands before handling the ingredients. Additionally, ensure that the vegetables or fruits you use for fermentation are fresh and free from any visible signs of spoilage.

Fermented foods should have a pleasant aroma and taste. If you detect an off odor, such as a strong rotten smell, or a sour taste that is too intense or unpleasant, it may indicate that the fermentation process went wrong. This could be due to improper temperatures, unsanitary conditions, or the presence of undesirable bacteria. To prevent this, ensure that you follow proper fermentation techniques, maintain a clean environment, and use fresh, high-quality ingredients.

In some cases, excessive gas production during fermentation can cause pressure to build up in the fermentation vessel, leading to leaks or even explosions. To prevent this, use appropriate fermentation vessels designed to release excess gas, such as fermentation lids with airlocks. Burp the fermentation vessel periodically to release accumulated gas and prevent pressure buildup.

If the fermentation process is taking longer than expected or there is no sign of fermentation, it could be due to various factors. One common reason is the absence of beneficial microorganisms or yeasts required for fermentation. Using a starter culture or a small amount of a previously successful batch can help kick-start fermentation. Additionally, ensure that the temperature is within the optimal range for the specific fermentation process.

Fermented foods can undergo texture changes during the fermentation process. Sometimes, vegetables can become softer or lose their crispness. This is a natural part of the fermentation process as the enzymes and beneficial bacteria break down the cell walls. If you prefer a crunchier texture, consider fermenting for a shorter period or using vegetables that are naturally firmer.

Fermentation is a fun way to experiment with bringing different flavors to preserving your garden harvest, with added health benefits. Start small and before you know it you’ll be a fermentation pro!

Ways to dehydrate food

Air drying: This is the simplest and most traditional method of dehydrating food. It involves placing sliced or chopped food on drying racks or screens in a well-ventilated area, preferably with good airflow and low humidity. It is a slower process compared to other methods, but it requires no special equipment.

Sun drying: Similar to air drying, sun drying involves placing food in direct sunlight to remove moisture. It is a popular method in regions with hot and dry climates. However, it requires consistent sunlight and protection from pests.

Oven drying: Using your oven is a convenient way to dehydrate food. Set the oven to its lowest temperature (ideally around 140°F or 60°C) and place the sliced or chopped food on baking sheets or wire racks. Keep the oven door slightly ajar to allow moisture to escape. This method is faster than air drying but not as energy-efficient.

Dehydrator: A food dehydrator is a specialized appliance designed for efficient and consistent food drying. It uses low heat and airflow to remove moisture from food. Dehydrators have multiple trays or shelves where you can place the food in a single layer. They often come with adjustable temperature settings and timers for precise control.

Microwave drying: While not as commonly used for dehydrating food, a microwave can be used for small quantities or quick drying. Place the food on microwave-safe plates or trays and use the microwave's defrost or low power setting to dry the food in short intervals, checking frequently to prevent overheating.

Troubleshooting issues with dehydrated food

Inadequate drying: If your food is not fully dehydrated, it may spoil or develop mold during storage. Ensure that you follow the recommended drying time and temperature for each type of food. Adjust the drying time if needed, considering factors like the thickness of the slices, humidity levels, and your specific dehydrator or drying method.

Over-drying: On the other hand, over-drying can result in food that is overly dry and brittle. This may lead to loss of flavor, texture, and nutrient content. To avoid over-drying, monitor the drying process closely and follow the recommended drying times. You can conduct periodic checks to determine the desired level of dryness.

Uneven drying: Sometimes, certain pieces of food may dry faster than others, resulting in uneven dehydration. This can happen if the food pieces are not of uniform size or thickness. To overcome this, try to slice or chop the food into consistent sizes and arrange them on the drying trays accordingly. Rotate the trays during the drying process to ensure even airflow and consistent drying.

Sticking or clumping: If the food pieces stick together or form clumps after drying, it may be due to excess moisture or inadequate spacing during the drying process. Ensure that you space the food pieces evenly on the drying trays, allowing sufficient airflow around each piece. If necessary, separate clumped pieces gently after drying.

Loss of color or flavor: Some foods may experience color or flavor changes during the dehydration process. To minimize these issues, consider pre-treating the food before drying, such as blanching vegetables or soaking fruits in lemon juice or other acidic solutions. Properly storing the dehydrated food in airtight containers or vacuum-sealed bags can also help preserve color and flavor.

How to use dehydrated food

Dehydrated food is incredibly versatile and can be used in a variety of ways. Dehydrated fruits make for delicious and healthy snacks. They can be enjoyed on their own or mixed with nuts, seeds, or granola for a homemade trail mix. Dehydrated vegetables can be used as crunchy and nutritious snacks too. Dehydrated vegetables and meats are perfect additions to soups, stews, and chili. Simply rehydrate them in hot water or broth and add them to your favorite recipes. They will infuse the dishes with concentrated flavors and nutrients. Dehydrated herbs, spices, and vegetables can be ground into powders and used as seasonings to enhance the flavor of your dishes. Sprinkle them on roasted vegetables, pasta, popcorn, or homemade sauces.

Preserving The Garden Harvest: Instructions For Water Bath Canning

What is water bath canning?

Water bath canning is a home food preservation method that involves processing jars of high acid foods in a large pot of boiling water. The process helps kill any bacteria, yeasts, or molds present in the food and creates a vacuum seal to prevent spoilage. It is a safe and accessible method for canning fruits, jams, jellies, pickles, and other high acid foods. And it doesn’t have to feel intimidating! In this guide, I will show you exactly how to water bath can your garden harvests for long term food storage.

Water bath canning has a long history that dates back to the early 19th century. The method was developed as a way to safely preserve and store food without the need for refrigeration or other modern preservation techniques.

The practice of using heat to preserve food can be traced back even further, with evidence of similar techniques being used by ancient civilizations. However, the specific process of water bath canning as we know it today began to take shape in the 1800s.

One of the key figures in the development of water bath canning was the French confectioner and brewer Nicolas Appert. In 1809, Appert invented a method of sealing food in glass jars, which he called "appertisation." He discovered that by heating food in sealed containers, it could be preserved for long periods without spoiling. His work laid the foundation for modern canning techniques.

In the United States, water bath canning gained popularity in the mid-19th century with the publication of various cookbooks and guides on home canning. One of the most influential figures in promoting canning methods was Maria Parloa, a renowned cookbook author and educator. Her book "The Appledore Cook Book" published in 1872 included detailed instructions for water bath canning.

During World War II, home canning experienced a resurgence as people sought ways to preserve food during rationing and shortages. Government programs and educational campaigns were launched to encourage home canning and provide information on safe canning practices.

Is water bath canning safe?

Yes, when done correctly and following recommended guidelines, water bath canning is a safe method of food preservation. Water bath canning is suitable for high acid foods, such as fruits, jams, jellies, pickles, and some tomato products. The high acid content in these foods creates an environment that inhibits the growth of harmful bacteria, such as Clostridium botulinum, which can cause botulism.

To ensure safety when water bath canning, it is important to follow tested recipes from reliable sources, such as government extension services, reputable canning guides, or trusted cookbooks. These recipes are specifically designed to provide the necessary acid levels and processing times to destroy any potential bacteria and ensure the safety of the preserved food.

Additionally, proper preparation and handling of jars, lids, and equipment are essential. This includes sterilizing jars and lids before filling them, using new lids for each canning session, and carefully following the instructions for filling and sealing the jars. It's also important to monitor and maintain the correct water bath canning temperature throughout the processing time.

WHat’s the difference between Water Bath Canning and Pressure Canning?

Some things like low-acid vegetables and meats can only be pressure canned due to their pH levels or density. These types of foods require the high temperatures and pressure generated in a pressure canner to ensure their safety. On the other hand, water bath canning is a suitable method for preserving high acid foods like fruits, pickles, and jams. The acidity in these foods inhibits the growth of harmful bacteria and makes them safe to can using the water bath method. It's important to note that you cannot substitute water bath canning if a recipe specifically calls for pressure canning. The two methods differ significantly in terms of temperature and pressure, and swapping them can compromise the safety and shelf life of the preserved food. To ensure food safety and quality, always follow the recommended canning method indicated in the recipe and consult reliable canning resources for guidance.

Water bath canning safety tips

Hot Food, Hot Jars

This means that your canning jars should be properly sanitized and preheated before filling them with your prepared hot food. Preheating the jars helps prevent thermal shock and ensures proper sealing of the lids. Additionally, using hot food minimizes the time that the filled jars spend at lower temperatures, reducing the risk of bacterial growth.

Be Clean To Be Safe

Cleanliness is key to prevent any contamination that could compromise the safety and quality of your canned goods. It is essential to have clean hands, clean jars, clean pots, clean utensils (preferably metal), and clean towels. This includes properly washing and sanitizing your hands before handling any food or equipment, thoroughly cleaning and sterilizing your canning jars, using clean pots for heating water, and using metal utensils that are easier to sanitize.

Trust Your Source

When it comes to canning, it is important to trust your source of information and recipes. Canning is a precise process that requires specific pH levels, processing times, and techniques to ensure food safety. It is not recommended to "wing it" or rely on untested recipes. Choose reliable and reputable sources that have a good understanding of the canning process, such as government extension services, trusted canning guides, or reputable cookbooks. Following tested recipes from trusted sources will give you peace of mind knowing that you are preserving your food safely.

Why should you use bottled lemon juice when canning?

Many canning recipes will call for lemon juice to increase the acidity of the recipe when the food itself does not have a high enough acid content to safely can. Bottled lemon juice will ensure you meet the specific acid levels required, since these acid levels can vary in fresh fruit. Vinegar may also be used to increase the acidity of foods. Prepare the recipe as written and do not improvise the amount of acid used.

SUPPLIES NEEDED FOR CANNING

LARGE POT + RACK

This will be your water bath canner. The rack keeps the jars off of the bottom of the pot. There are canning specific pots available to buy but any pot large enough to hold your jars and be covered by at least an inch of water will work.

POT TO PREPARE YOUR FOOD IN

Often the food you are cooking may expand as it boils, so choose a pot much larger than you think you’ll need to allow a lot of extra space. Since we are canning high-acid foods, you should not use aluminum or cast iron as they are reactive. Stainless steel is the best choice, with a thick bottom to prevent sticking and burning.

JAR LIFTER

This tool makes it safe and easy to move your extremely hot and full jars from counter to canner and back again.

WIDE FUNNEL

For filling your jars without making a mess on the outside of the jar or rim.

TOWELS

A stack of very clean dishtowels for spills will make all the difference.

CANNING JARS

An obvious one, but there are many sizes and brands, and each size will require a different processing time. Jars can be used but canning lids usually are not.

TWO PIECE CANNING LIDS

You will have a flat lid which may only be used once and a ring which can be reused for as long as it is not rusty or damaged. Flat lids can be purchased separately from rings and jars, so you can reuse last years jars and rings and just replace the lid.

BASICS OF WATER BATH CANNING

The exact steps you follow will vary depending on the recipe you are using, but the fundamentals will stay the same. Preparation in advance will make all the difference in whether your first canning experience is chaotic or calm.

Set aside your rings and lids, and place your empty jars into your canner. Cover the jars with water, at least one inch above the top. Bring this to a boil and then simmer to sanitize the jars.

While the jars are simmering, prepare your recipe.

Remove the jars from the water and using your wide funnel fill the jars with the prepared food. Leave the appropriate amount of headspace (empty room at the top) specified in your recipe for expansion.

Use a non-metallic tool, such as a bubble remover or a plastic spatula, to gently remove any trapped air bubbles in the jars.

Wipe any food splatter from the rim of the lid with your clean dishtowel and cover the jars with the lids and rings, twisted just finger tight.

Place your full jars back in the water bath, cover it and bring back to a boil. The processing time will depend on the type of food being canned and the altitude of your location. Follow the processing time indicated in the recipe to ensure the food is safely preserved.

Remove the jars from the water bath and place them on a towel-lined area of the countertop where they can cool for 24 hours, so as not to disturb the sealing process. The jar lids will pop as they seal.

After 24 hours has passed, check the seal by removing the ring and holding the jar by its lid. The lid should be on very firmly. If it didn’t seal - your food is still edible, but it is not shelf stable and must be kept in the fridge and eaten right away.

Label your jars with the contents and date and store in a cool dark place. You should not put the rings back on at this point - they aren’t necessary once the jar has formed a proper seal, and could prevent you from noticing a false seal.

High acid canned food is good for about one year when properly stored.
