I recently discovered how convenient and tasty instant refried beans are. Perfect for a quick snack when I don't have much else ready, and very simple to make in large quantities.
I started by soaking and cooking a big crock pot full of pinto beans, with onions and garlic. After draining them, I mixed it all up with my stick blender, using reserved bean liquid to accretive the right consistency.
I leave out the fat both for caloric reasons and because fats do not dehydrate well.
After I have my mashed beans I spread them onto my trays (lined w non stick sheets) to an even quarter inch thick.
Dehydrate at 125 degrees for about six hours. The beans crack and break apart while they dry, like a mud puddle.
I ran the crumbles through the blender, to make them fine. To re-hydrate, I just mix boiling water into some bean crumbles until it seems to be the right consistency, and let it stand, covered, for ten minutes or so. Delicious!
