Waste not, want not. That saying has never been truer. After canning 2 batches of whole tomatoes, we were left with a large amount of skins. So we looked up and found a way to preserve the skins and use them in other things like tomato paste.
1. Take skins and dehydrate over night.
2. Put skins in a processor and process. I also put mine in the bullet to get to a powder.
