Still, my favourite was lentil soup.
And it's delicious. Have I mentioned how great it tastes?
Step 1: Make lentil soup. I made the soup slightly thicker than I normally would, thinking that it would just save time in the long run as the dehydrator would only be removing all of the water in the soup anyway. The soup was seasoned well. You'll find all kinds of lentil recipes on the internet, but it's a pretty easy ingredient to cook with on the fly. The only rule of thumb here is to keep the fat content low since we're going to be dehydrating the soup. In this case I didn't use a stock as the base, rather I used seasoning, onions and the lentils themselves for flavour.
Step 2: Put the lentil soup in the dehydrator. This is where the extra fruit "roll up" trays I bought came in handy. They can be used to dry all kinds of liquids. Spread the soup on the trays as evenly as possible. The edges can be slightly thicker since they tend to dry faster. The lentil soup should be about a 1/4" thick. I believe I dried the soup at 140 overnight.
Step 3: Marvel at the amazing thing you've created. The pieces were bigger than what's shown in the pictures, I broke them up in order to store it better. The lentil soup came out almost cracker like. In fact, I ate a couple of dried pieces and I think it really would make an excellent cracker if I could fine-tune the recipe. Seal all of the pieces in an air-tight bag or jar.
Step 4: Enjoy a hot cup of previously made lentil soup. We enjoyed this when we were camping, and I rehydrated it with several vegetables which made a hearty soup. With the high protein content, we didn't need to add meat to the meal. It took about 10 minutes to rehydrate, and I just kept adding water until it had the right consitency.
I'll do this again, even if we're camping somewhere that food is readily available. The resulting meal is delicious and healthy, not to mention completely satisfying. It took almost no room in our camping gear, and dried while we slept.
Have you tried any soups in a dehydrator? I'd love to hear your stories.
