When I had way too many tomatoes last year, I started dehydrating them. The cherry and grape tomatoes, I just cut in half and once dried, stored them in a canning jar. I use them in recipes calling for sun dried tomatoes. For the larger tomatoes, once dried, I put them thru my food processor until they became a powder or close to it. I use it when my sauces are too runny or just to add a bit of punch in my soups. The nice thing about it is, they last for a long time whether you put them into the freezer or like me, into a canning jar and into my cabinet. They won't spoil.
