I love dehydrated tomatoes. They put quite a splash into a lot of dishes, are easy to preserve, easy to store, and easy to use. I canned (in glass) some tomatoes, but have only used the dehydrated. I used Amish Paste tomatoes for dehydrating, and they are divine.

What do you mean by open kettle? Next up on my list of how-to as a prepper is the pressure canner, so that not everything I can has either vinegar, sugar, or both. I'm so sick of pickles already.
