#STERILIZING CANNING JARS CRACKED#

Everyone was fine, thankfully, but it was a stark reminder of how water temperature and jar temperatures can be the difference between a safe canning experience and a scary one. Our son wasn’t paying attention to what his dad was doing and randomly poured cold water into a hot canner with one jar left in it. We were using multiple canners, and at the time my husband made his request, he was emptying one hot canner which had recently finished processing. My family and I were in the kitchen canning this summer, and my husband asked our teenaged son to put water in the canner. I learned a hard lesson this year when it came to water temperature and jars.

When I went to pull them from my pressure canner, the jars had cracked in the middle, and the bottoms would be left in the canner as I used jar grabbers to pull the top of the jar out. I’ve added cold jars to a canner in the past and have been devastated after they finished processing. Be sure you allow the jars to reach room temperature again before processing them.Īlso, be sure to add fresh water to the canner because this will help to keep the jars from cracking as the fresh water heats in the canner. It’s normal to put them in the fridge for the night and resume canning the next morning. One example is if you’re canning late at night, and you run out of energy before you get all of your jars processed. I’ve been canning for many years now, and I’ve learned the hard way about how drastically temperatures can impact a jar. The reason being is if you introduce a jar to water or other contents which are heated to higher temperatures, it can cause the jar to break. It’s still recommended to heat canning jars before filling them with your recipes or before you add them to a canner. When the time is up, leave the jars in the pot until you’re ready to use them.

Close the lid and lock it making sure the valve is set to seal. Make sure the rack is in the bottom of the instant pot to support the jars.Īdd one cup of water to the Instant Pot and place your jars inside. The final option for sanitizing your jars is in the Instant Pot. The dishwasher will wash, dry, and sanitize your jars all in one easy push of a button. Put them in your dishwasher to wash and choose the sanitizing option. If you have a dishwasher which has a sanitation setting, you can just use it. This is perhaps the easiest way of sterilizing your canning jars. When the time is up, turn off the oven, and let the jars to remain in the oven until you’re ready to fill them.īe sure you use oven mitts when handling the jars because they’ll be hot. Put the pan in the oven and allow it to bake for 20 minutes. Put the jars in a deep pan such as a roasting pan or other deep dish safe for baking. Preheat the oven to 225° Fahrenheit (110º Celsius). Sterilizing jars in the oven is another easy method.

When the time is up, turn the stove off, and allow the jars to sit in the water until you’re ready to fill them.īe sure to remove them using jar grabbers because they’ll be extremely hot to the touch. The time will depend upon your elevation level. Allow the jars to boil in the water for 10-16 minutes. Turn your stove on high and bring the water to a boil. Pour warm water over the jars until they’re fully submerged and have an inch of water over the top of each jar. Start the process by placing the jars in the canner. Lids can be used safely at room temperature, and the rings don’t need to be sterilized because they don’t come in contact with the food inside the jar. You don’t need to sterilize your lids and rings. Therefore, it’s a good idea to go ahead with the sterilizing process. However, when making jams and jellies the processing time is approximately five minutes, which is not long enough for the jars to be considered sterile. If you’re processing the jars in a boiling water canner for longer than 10 minutes or if you’re pressure canning the jars, they don’t need to be sterilized. The answer to this question is yes and no.
