Making "thick" soups is a regular thing with us. Split Pea, MultiBean, etc. "Moosewood" is our source for recipes, but any favorite will work. Cashew Chili is another. Morrocan Stew yet another.
Once cooked to perfection, they go onto teflon sheets, on the dehydrator trays, at about 1/8" thick, for about 6 hours. We portion each sheet to make a 12 ounce serving for one when rehydrated.
Once dried, we pry them off, break up the pieces by hand, and then put them into the blender for a "buzz" or two. This knocks off the edges and points that would perforate a ziplock. If you "buzz" them too long they turn into powder. They are still good, but they have no texture. We like lumps in our soups.
In camp, add boiling water, stir it, clap your hands three times, and dig in. It's fast.
