Making true “sun-dried” tomatoes can be done in a very dry, hot climate in the summertime such as in parts of the southwest and west. Here in the Northwest it is far too moist to dry anything out in the open so we need to use a food dehydrator. Roma tomatoes work best for this recipe because of their low moisture content. Dried tomatoes can be rehydrated with hot water to make tomato sauce or pizza sauce. They are great added to soups that will be pureed. I also use them to make savory crackers and flatbreads.
