Step 8: Tomato Goodness
I place the jars on a dry kitchen towel with plenty of space around them.
Let them cool for several hours. As they cool down, the lids start to shrink and that's what creates the vacuum seal. Take a look at the lids periodically and you'll see that the bump in the middle of the lid becomes almost a little dimple. Then you know they are safe to store. If any jar doesn't seal, store it in the refrigerator and eat soon. The rest of the jars can be stored for many months in a dark cool place.
Yum! Yum! Yum!
