I have just completed preparing dehydrated meals for an upcoming trip. I am new to dehydrating so I am hoping for some advice on rehydrating on the trail. My intention is to rehydrate these as freezer bag meals. For instance, I have dehydrated a corn chowder that was 22oz pre dehydration and 5 oz after. Also did East Indian Curry Chicken that was 28 oz pre dry and dehydrated weight was 6oz. My logic says add 17 and 22 oz of water and presto, its back hydrated. Is this right? Is it just trial and error or are there some better guidelines to go by? Help please.
