A friend offered to introduce me to canning. I want to learn so accepted. We picked and canned tomatoes today. But, I'm concerned about the way she sterilized the jars... in the dishwasher. The jars, filled with tomatoes, were not then boiled for at least 10 minutes or processed in a pressure cooker. They're now sealed. I'm worried that they're not sterile. Can I submerge them in water and boil them for whatever time is recommended with the sealed lids left in place? Note, it's been less than a day.
All advise is greatly appreciated!
