In order to actually sterilize jars, they need to be submerged in (covered by) boiling water for 10 minutes. When the process time for canning a food is 10 minutes or more (at 0-1,000 feet elevation), the jars will be sterilized DURING processing in the canner.
Do jars need to be boiled before canning?
Jars do not need to be sterilized before canning if they will be filled with food and processed in a boiling water bath canner for 10 minutes or more or if they will be processed in a pressure canner.

Why turn jars upside down?
The thinking behind the inverting is that the jam/jelly—being still at a temperature to destroy spoiler micro-organisms—will sterilize the underside of the sealing disc, and the little amount of air trapped under the lid. A vacuum can form if the jars are hot and the contents are at least 165 F/74 C.
How long do you boil jars to seal them?
Place lids on jars, screw on rings and lower jars back into the pot of boiling water. The water should cover the jars; if not, add more. Boil jars for 10 minutes. Transfer jars to a folded towel and allow to cool for 12 hours; you should hear them making a pinging sound as they seal.

Is dry canning safe?
No, dry canning isn’t safe. In fact, it shortens the food’s shelf life. Unfortunately, the jars can’t handle the intense heat which may cause micro-fractures, leading to the jar breaking. The heat also releases the natural moisture of the jar’s contents which bring a risk of mold.

Two-piece lids are recommended for canning foods. According to So Easy to Preserve, “When using two-piece lids, place the treated lid on the filled jar, center it, and hold it in place with fingers. Then screw down the band fingertip tight. These lids should not be tightened further after processing.”
What is a self sealing canning jar?
The common self-sealing lid consists of a flat metal lid held in place by a metal screw band during processing. The underside of the lid contains an applied sealing material that, when heated during canning, softens and flows slightly to cover the jar-sealing surface while still allowing air to escape from the jar.
How do you prepare jars for canning?

What happens if you forgot to remove air bubbles when canning?
“When air bubbles are not removed, the air trapped by the food will essentially add to the headspace. Too much headspace can lead to seal failures.” Opt for wooden or plastic tools (like Ball’s official “bubble freer,” shown here) when shifting the contents to remove headspace.
Can I reuse snap lids for canning?
The simple answer is no: Canning lids are designed for one-time use. Using them more than once may result in your jars not sealing properly. These lids have a special sealing compound around the rim that is only good for one use.

Answer. Headspace is the distance between the surface of food and the underside of the lid. Leaving the specified amount of headspace in a jar is important to assure a vacuum seal. If too little headspace is allowed the food may expand and bubble out when air is being forced out from under the lid during processing.
