To begin, gather your canning jars and wash them thoroughly with hot, soapy water. Rinse them well and place them in a large pot or boiling water canner. Fill the pot with enough water to cover the jars by at least one inch, and bring the water to a boil. Allow the jars to boil for 10 minutes to ensure that they are fully sterilized. If you are at a higher altitude, adjust the boiling time according to your altitude’s guidelines.
Another option for sterilizing your canning jars is to use your dishwasher’s sterilization cycle. Simply load your jars into the dishwasher and run them through a sterilization cycle. This method is especially convenient if you are short on stove space or if you have a large number of jars to sterilize. Regardless of which method you choose, be sure to handle your sterilized jars carefully to avoid recontamination.

When it comes to canning, filling and sealing the jars properly is crucial to ensure that your food stays fresh and safe to eat. In this section, we’ll cover the steps involved in filling and sealing your canning jars.
Adding Food to the Jars
Before you start filling your jars, make sure your recipe is ready and your food is prepared. Whether you’re making jams, jellies, preserves, chutney, or any other canning recipe, the process is generally the same. Here’s what you need to do:
- Sterilize your jars, lids, and screw bands according to the manufacturer’s instructions.
- Place the jars on a clean towel or rack, and fill them with your prepared food, leaving the recommended headspace (usually 1/4 to 1/2 inch).
- Use a clean, non-metallic utensil to remove any air bubbles from the jars.
- Wipe the rims of the jars with a clean, damp cloth to remove any food residue or debris.
- Place the lids on the jars, making sure the sealing compound is in contact with the rim of the jar.
- Screw the bands onto the jars until they are fingertip tight.
Securing the Lids and Screw Bands
Once you’ve filled your jars with food and added the lids and screw bands, it’s time to secure them properly. Here are some tips to help you ensure your jars are sealed correctly:
- Don’t overtighten the screw bands, as this can prevent air from escaping during processing and lead to seal failure.
- Make sure the lids are centered on the jars and the sealing compound is in contact with the rim of the jar.
- Use a jar lifter to place your jars in the canner, and make sure they are covered with at least one inch of water.
- Process your jars according to your recipe’s instructions, and let them cool completely before checking the seals.
- To check the seals, press down on the center of the lid. If it doesn’t move, the jar is sealed. If it pops up and down, the jar is not sealed.
By following these steps, you’ll be able to fill and seal your canning jars like a pro, and enjoy your homemade preserves, jams, and other canned goods for months to come.
Processing and Storage
Water Bath and Pressure Canning
Once you have filled your sterilized jars with your homemade preserves, it’s time to process them. You have two options: water bath canning or pressure canning. Water bath canning is suitable for high-acid foods such as fruits, pickles, and tomatoes. Pressure canning is necessary for low-acid foods such as vegetables, meat, and fish.
To water bath can, place your filled jars in a large pot of boiling water. Make sure the jars are fully submerged and that there is at least one inch of water covering the jars. Process the jars according to the recipe’s recommended processing time, adjusting for altitude if necessary.
To pressure can, place your filled jars in a pressure canner with the recommended amount of water. Follow the manufacturer’s instructions for operating the canner and process the jars according to the recipe’s recommended processing time, adjusting for altitude if necessary.
Cooling and Testing Jar Seals
After processing, remove the jars from the canner and place them on a towel to cool. As the jars cool, you will hear a “ping” sound indicating that the jar has sealed. Once the jars have cooled completely, test the seals by pressing down on the center of the lid. If the lid pops up and down, the jar did not seal properly and should be refrigerated and consumed within a few days.
Storing Canned Goods
Properly processed and sealed jars can be stored in a cool, dark place for up to a year. Label each jar with the contents and date of processing for easy identification. Check jars periodically for any signs of spoilage such as mold, off-odors, or discoloration. If you notice any of these signs, discard the contents and sanitize the jar before using it again.
Remember to always follow safe canning practices to ensure the safety and shelf life of your canned goods. Happy canning!
