Do all canning jars have to be sterilized?
If you are wondering whether you should sterilize jars before filling them up with delicious preserves, the solution is based on the recipe’s processing time. “Jar sterilization is not needed ahead of canningunlessthe recipe used includes a processing time significantly less than 10 minutes,” explains Stephen Galucki, Manager of R&D Fresh Preserving at Newell Brands. “In recipes where in fact the processing time is 10 minutes or longer, sterilization is achieved through the food processing step.” Additionally, you do not ever have to pre-sterilize jars if you are pressure canning.

How exactly to sterilize canning jars
When you could find “hacks” online that tell you firmly to sterilize jars in the dishwasher or microwave, there’s only 1 USDA-approved way for sterilizing jars. “The only method to sterilize jars is by boiling them in water for at the least 10 minutes at an altitude of 0 to at least one 1,000 feet, with more time added at higher elevations,” says Galucki.
1. Gather your equipment
To sterilize glass canning jars, you may need aboiling water canneror perhaps a stockpot with a rack the pot must be at the very least 2 inches taller compared to the jars you’re processing. Ajar liftermay also can be found in handy, but a couple of kitchen tongs will continue to work, too.
2. Create your pot
Place the rack in the canning pot and arrange your jars along with it, facing right side up. It is important to work with a rack, otherwise the bubbles that form once the water boils may cause the jars to bounce around and bang into one another, which can result in cracks.
3. Cover the jars with water
Next, fill the pot with warm water. It’s easiest to pour water in to the jars first, then your surrounding area otherwise, they’ll float up. You will want to fill the pot before water reaches least 1 inch outrageous of the jars.
4. Process for 10 minutes
Place your pot on the stove and turn the burner on high. Bring the water to a roiling boil and process the jars for 10 minutes to sterilize them at altitudes around 1,000 feet. In the event that you live at an increased altitude, you will have to add one additional minute for every additional 1,000 feet of elevation.

After 10 minutes is up, your jars are sterilized easy, right? From here, it is possible to take them off from the water utilizing the jar lifter, carefully dump out any water, and fill them together with your processed foods. Be cautious handling the jars, as are going to quite hot!
If you are not quite prepared to fill the jars yet, it is possible to simply switch off heat and leave them in the water until it is time to fill.
Wait, think about the lids?
Canning lids, however, shouldn’t be sterilized in boiling water. The high temperature can in fact harm the sealing ring on the lower of the lid, causing it never to seal properly during processing.
“Ball lids need not be sterilized outside the processing time or pre-warmed ahead of use,” explains Galucki. Instead, it is possible to simply wash the lids with warm, soapy water before putting them onto the jars.
