How to Prepare Jars for Canning
Equipment
- Water bath canner or large stockpot with rack
- Jar Lifter
- Home canning funnel
- Bubble freer or headspace tool
- Clean cloth or paper towel
Ingredients
Jars, lids and screw bands
- Glass canning jars (check for cracks or chips)
- New flat lids
- Bands (rings)
Water
- Hot tap water (for boiling or simmering jars)
Instructions
- Wash jars, lids and bands thoroughly in hot, soapy water and rinse well.
- Dry jars on a rack or clean towel, and rinse bands and lids, then set aside at room temperature.
- If your recipe’s processing time is less than 10 minutes, sterilize jars by placing them upright in a water bath canner with hot water covering jars by 1‑inch, then boil for 10 minutes (add 1 min per 1,000 ft altitude). Remove and drain each jar just before filling.
- If processing time is 10 minutes or more (or you’re pressure canning), sterilization isn’t required the processing itself sanitizes the jars, but pre‑heating jars in simmering water is recommended to avoid breakage.
- Keep jars hot until ready to fill (e.g. leave them in the simmering water or hot dishwasher on sanitize setting).
- Fill each jar one at a time with hot prepared food, leaving recommended headspace (typically ¼″ for jams/jellies, ½″ for fruits/pickles).
- Remove air bubbles using a spatula, chopstick or headspace tool.
- Wipe jar rims clean with a damp cloth to ensure good seal.
- Center lid over jar and apply band fingertip‑tight not overly tight, so air can vent during processing.
- Process filled jars according to tested recipe instructions (e.g. in boiling water bath or pressure canner).
- Once processing time is complete, remove jars and rest them undisturbed for 12–24 hours without retightening bands.
- Check seals: properly sealed lids don’t flex when pressed and cannot be easily lifted off. If seal fails, refrigerate and use soon or reprocess with new lid.
- Before storage, remove bands and wash jars to remove food residue; label with date and product and store sealed jars in a cool, dry, dark place (50–70 °F) for up to 12–18 months.
