Prepare Your Gear: Wash & heat your jars and lids. 2. Create Your Recipe: Use a tested recipe for home canning, see the Ball Blue Book guide to preserving or FreshPreserving.com.3. Preserve Your Foods: Fill your clean jars. Boil in waterbath or pressure canner for time specified in recipe. See bottom panel for complete instructions. Ball Complete Home Canning Instructions: What You Need: Canning recipe - see Ball Blue Book guide to preserving or FreshPreserving.com for recipes; Fresh ingredients; Jars and two-piece lids (lids and bands). Prepare Your Gear & Create Your Recipe: Wash jars, lids and bands in hot, soapy water. Rinse well. Jars must be kept warm until ready to use, in order to minimize risk of breakage when filling with hot food. You can heat them in the pot of simmering water, or in a heated dishwasher. Prepare food using fresh ingredients and a tested recipe for home canning. Waterbath Canning: To Can: Tomatoes, salsa, pickles, jellies, jams, fruits (whole, sauces, chutneys, pie fillings, etc.) and other high-acid foods. You Also Need: Ball 21-Quart Waterbath Conner or equally large stockpot with a Ball Canning Rack, or for small batches, a Ball Canning Discovery Kit. Prepare Jars: Fill pot with enough water to cover jars with at least 1 inch of water and heat to simmer (180 degrees F). Fill each hot jar with prepared food. Follow canning recipes for correct fill-level. Each jar needs space between the food and the rim (headspace) to allow for food expansion. Tip: Air bubbles inside jar can impact cooking effectiveness. Remove bubbles by sliding a small non-metallic spatula inside the jar, gently pressing food against the side of the jar. Wipe any food from the rim of the jar. Center new lid on the jar, then twist on band just until fingertip tight. Ensure bands are not over-tight - air inside jar must be able to escape during canning. Process Jars: Place filled jars onto rack, then lower into simmering water, ensuring jars are covered by 1 inch of water. Cover with lid, and heat to steady boil. Boil jars for the time specified in recipe, adjusting for altitude (see chart). Turn off heat and let jars stand in water for 5 minutes. Remove from water and cool jars upright on wire rack or towel on countertop for 12 hours. Tip: After removing jars from the canner, do not re-tighten bands that may have come loose during canning, so as not to interfere with the sealing process within the first 12 hours. Pressure Canning: To Can: Green beans, carrots, beets, meats, fish or other low-acid foods. You also need: Pressure Canner. Prepare Jars: Heat 3 inches of water to simmer (180 degrees F) and follow manufacturer instructions. Fill each hot jar with prepared food. Follow canning recipe for correct fill-level. Each jar needs space between the food and the rim (headspace) to allow for food expansion. Tip: Air bubbles inside jar can impact cooking effectiveness. Remove bubbles by sliding a small non-metallic spatula inside the jar, gently pressing food against the side of the jar. Wipe any food from the rim of the jar. Center new lid on the jar, then twist on band just until fingertip tight. Ensure bands are not over-tight - air inside jar must be able to escape during canning. Process Jars: Place filled jars onto rack. Canner should contain 2 to 3 inches of simmering water. Lock canner lid into place. Turn heat to medium-high and open vent. Bring to boil and vent a steady stream of steam for 10 minutes. Put weight on vent and adjust heat to achieve 10 pounds pressure, adjusting for altitude (see chart). Process for time listed in recipe, keeping pressure steady. Follow manufacturer's guidelines for cooling and removing pressure canner lid. Remove from water and cool jars upright on wire rack or towel on countertop for 12 hours. Tip: After removing jars from the canner, do not re-tighten bands that may have come loose during canning, so as not to interfere with the sealing process within the first 12 hours. Check the Seal: Press on center of cooled lid. If jar is fully sealed, the lid will not flex up or down. If the lid flexes, the jar did not seal properly. You may refrigerate for immediate use. Or for directions on how to safely re-process the jar, see FreshPreserving.com or the Ball Blue Book guide to preserving for detailed instructions. Store sealed jars in pantry for up to 1 year. Jars may be stored without bands, or you may clean underside of bands to ensure no moisture is trapped during storage. Enjoy your homemade food or give as a gift.
