Fill water bath canner at least half-full with water. Cover and maintain a simmer (180°F) until jars are filled and placed in canner.
Check jars, lids, and bands for proper functioning. Jars with nicks, cracks, uneven rims, or sharp edges may prevent sealing or cause jar breakage. The underside of lids should not have scratches or uneven or incomplete sealing compound as this may prevent sealing. Bands should fit on jars. Wash all in hot, soapy water and dry well.
Pre-heat your canning jars in hot (180°F) water. Keeping jars hot prevents them from breaking when filled with hot food. Leave lids and bands at room temperature for easy handling.
Use a Jar Lifter to remove the pre-heated jar. Fill jars one at a time with prepared food using a Jar Funnel, leaving headspace recommended in recipe. Remove air bubbles, if stated in the recipe, by sliding the Bubble Remover & Headspace Tool or rubber spatula between the jar and food to release trapped air. Repeat around jar 2-3 times. For successful sealing, you need to leave the correct amount of space between the food and the rim of the jar.
Wipe the rims and threads of the jars using a clean, damp cloth to remove any food residue. Center lid on the jar, allowing sealing compound to contact the jar rim. Apply band and adjust until fit is fingertip-tight. Place jar in canner. Repeat steps 4 and 5 until all jars are filled. Ensure water covers jars by 1-2 inches.
Place lid on water bath canner and bring water back to a rolling boil. Begin processing time.
Process in the boiling water for 15 minutes. When complete, shut off heat and remove the lid. Allow jars to rest in canner for 5 minutes to be acclimated to the outside temperature.
Move jars from canner and set upright on a towel. This will prevent jar breakage that can occur from temperature differences. Leave jars undisturbed for 12 to 24 hours. DO NOT retighten bands as this may interfere with the sealing process.
Inspect lids for seals. There should be no flex when center is pressed. Remove the bands and attempt to lift lids off with your fingertips. Properly sealed lids will remain attached. If a lid fails to seal within 24 hours, immediately refrigerate the product. Clean canning jars and lids, label and store in a cool, dry, dark place for up to for up 18 months.
