Water bath canning, also known as boiling water canning, is one of the most accessible and effective methods for preserving high-acid foods like fruits, jams, jellies, and pickles. Using just a few key tools and some careful attention to process, you can safely enjoy the flavors of summer all year long.
What Is Water Bath Canning?
A boiling water canner is typically made from aluminum or porcelain-covered steel and includes a fitted lid and removable rack. The process involves submerging sealed jars in boiling water for a specified time, which eliminates harmful microorganisms and creates a vacuum seal that keeps food shelf-stable for up to a year or more.
Before getting started, it’s important to ensure the canner is deep enough to keep at least one inch of briskly boiling water over the top of the jars. For processing times over 30 minutes, this increases to two inches. Always check with your stovetop manufacturer to make sure your range is suitable for canning, especially if you have a smooth-top range.
Step-by-Step Guide to Water Bath Canning
- Preheat Water: Place the canning rack in the bottom of the canner and fill it half full with warm water. Preheat to 140°F for raw-packed foods or 180°F for hot-packed foods.
- Prepare Jars and Food: While the water is heating, wash and fill your jars with food, ensuring proper headspace.
- Load Jars: Use a jar lifter to place the jars upright into the canner. Add hot water if needed so the water level is at least 1 inch above the jars.
- Bring to a Boil: Cover the canner with the lid and bring the water to a vigorous boil.
- Start the Timer: Once boiling begins, start timing according to your recipe’s instructions. Keep the water at a gentle but complete boil for the entire process.
- Cool and Store: After the time is complete, turn off the heat, remove the lid, and wait 5 minutes before carefully lifting jars out. Let them cool undisturbed for 12–24 hours before labeling and storing.
This method is reliable and recommended by the USDA and University of Georgia Cooperative Extension for foods with high acid content. Always follow updated, research-tested recipes for safe results. Contact our office to purchase So Easy to Preserve for tested and safe recipes.
