,,,dehydrating tomatoes. In my effort to not waste food, I took 2 tomatoes that were a bit on the soft side and am dehydrating them. It's only one tray, but with our solar electric, it doesn't cost anything to run the dehydrator. That means there is a net savings of two tomatoes. Okay, I was dying to dry tomatoes so I could pulverise them into a powder. I have been wanting to do that for a while and our tomatoes are not ripe yet. Why is it, that when you want lots of tomatoes there aren't any, but when you have tons, you can't figure out what to do with them?
