How To Safely Can Food At Home


Home canning is a method of preserving food that allows you to enjoy the flavors of fresh produce all year round. By following proper techniques, you can safely can a variety of fruits, vegetables, and other foods. In this article, we will guide you through the process of safely canning food at home, ensuring the preservation of quality and minimizing the risk of foodborne illnesses.

Benefits of Home Canning

1. Food Preservation

The primary benefit of home canning is preserving food for extended periods. Canning allows you to store seasonal fruits and vegetables when they are abundant and at their peak freshness. By sealing them in jars, you can maintain their flavor, nutritional value, and texture.

2. Cost Savings

Home canning can result in significant cost savings. By canning your own produce, you can take advantage of sales, discounts, or homegrown harvests. Additionally, canning allows you to reduce food waste by preserving excess produce that might otherwise go unused.

3. Control over Ingredients

When you can food at home, you have full control over the ingredients used. You can choose organic, pesticide-free, or locally sourced produce, ensuring the quality and healthfulness of your canned goods. It also allows you to customize recipes according to personal taste preferences and dietary restrictions.

Equipment and Supplies Needed for Home Canning

Before you begin home canning, ensure you have the necessary equipment and supplies:

1. Canning Jars and Lids

Choose canning jars specifically designed for home canning, such as Mason jars. Ensure the jars are free of cracks or chips. Use new lids with rubber seals to ensure proper sealing.

2. Canning Pot or Pressure Canner

Depending on the food you are canning, you’ll need either a boiling water canner or a pressure canner. A boiling water canner is suitable for high-acid foods like fruits, tomatoes, and pickles, while a pressure canner is necessary for low-acid foods like vegetables, meats, and soups.

3. Utensils and Tools

Gather essential utensils, including a canning funnel, jar lifter, bubble remover, and a non-metallic spatula. You’ll also need a large pot for preparing the food and a kitchen timer for accurate processing times.

Steps for Safe Home Canning

Follow these steps to ensure safe home canning:

1. Choose Fresh and High-Quality Ingredients

Select fresh, ripe, and high-quality ingredients for canning. Avoid using overripe or damaged produce as it may affect the quality and safety of the final product.

2. Prepare Jars and Lids

Wash the jars, lids, and bands in hot soapy water. Rinse them thoroughly and place them in boiling water for a few minutes to sterilize. Keep the jars warm until ready to use.

3. Prepare the Food

Wash, peel, and chop the fruits or vegetables according to the recipe. Follow the specific instructions for blanching, peeling, or precooking, if required.

4. Fill and Seal the Jars

Using a canning funnel, carefully fill the prepared jars with the food, leaving the recommended headspace. Wipe the jar rims with a clean, damp cloth, place the lids on top, and secure them with bands. Ensure the bands are fingertip tight.

5. Process the Jars

Place the filled jars in a canning pot or pressure canner, ensuring they are submerged in water or as per the specific instructions for your canner. Process the jars for the recommended time and at the proper temperature, following tested recipes for each food type.

6. Cool and Store the Jars

Once the processing time is complete, turn off the heat and allow the jars to cool naturally. Avoid any sudden temperature changes. After cooling, check the seals by pressing the center of each lid. Store the properly sealed jars in a cool, dark place.

Safety Tips for Home Canning

Follow these safety tips to ensure successful and safe home canning:

1. Use Tested Recipes

Always use tested canning recipes from reliable sources, such as the National Center for Home Food Preservation or reputable canning cookbooks. These recipes have been scientifically tested to ensure the correct acidity, processing times, and temperatures for safe canning.

2. Properly Sterilize Jars and Lids

Thoroughly clean and sterilize the jars and lids before filling them with food. Sterilization can be done by boiling them in water or using a dishwasher’s sterilizing cycle.

3. Follow Processing Times and Temperatures

Adhere to the recommended processing times and temperatures specified in the recipe. These guidelines are essential for destroying harmful bacteria, molds, and yeasts and preventing spoilage.

4. Check for Seal and Spoilage

After cooling, check the jars for a proper seal. The lids should be concave and not move when pressed. Discard any jars that show signs of spoilage, such as bulging lids, unusual odors, or mold growth.


Home canning is a rewarding and cost-effective way to preserve your favorite foods. By following proper techniques and safety guidelines, you can safely enjoy your home-canned goods throughout the year. Remember to choose high-quality ingredients, use tested recipes, and follow recommended processing times and temperatures for a successful canning experience.


Q: How long can home-canned food be stored? A: When properly canned and stored in a cool, dark place, home-canned food can typically be stored for up to one year. However, it’s recommended to consume them within 6 to 8 months for optimal quality.

Q: Can any recipe be used for home canning? A: Not all recipes are suitable for home canning. It’s important to use tested canning recipes specifically designed for preserving food safely. These recipes consider factors like acidity, processing times, and temperatures to ensure safe preservation.

Q: Can I reuse jars and lids for canning? A: While jars can be reused as long as they are in good condition, lids should not be reused. The sealing compound on lids becomes less effective after one use, increasing the risk of spoilage.

Q: Can I adjust the spices or seasonings in canning recipes? A: It’s generally recommended to follow canning recipes as closely as possible, including the specified amounts of spices and seasonings. Altering the ingredients may affect the safety and quality of the final product.

Q: Are there specific foods that should not be canned at home? A: Certain low-acid foods with a pH level above 4.6, such as garlic, mushrooms, and pumpkin, require specialized equipment and techniques for safe home canning. It’s best to refer to tested recipes and reliable sources for guidance on canning specific foods.
