I have a dehydrator and done some fruits (apples,bannanas, peaches,pears and such),But I want to try dehydrate veggies and meals and was wondering how does one knows how much water to use in rehydrating them. I did dried some Ragu Spag Sauce some months back and when I tried to rehydrate,I think I used too much water and was ruined, Good thing I was home before trying or I might of been pretty hungry. Thanks for any input.
