Some canning recipes call for sterilized jars, others don't. Here's what you need to know.
If the jars of food will be processed in a boiling water bath or pressure canner for 10 minutes or longer, the jars should be clean but do not need to be sterilized.
If the jars of food will be processed for less than 10 minutes, sterilize them by covering them with water, bringing the water to a boil, and boiling for 10 - 15 minutes.
