Crockpot Refried Beans

I really need to try this recipie I found on realmomkitchen.com. We use that canned stuff all of the time!

•3 cups of dry pinto beans (rinsed)
•1 onion, diced
•9 cups of water
•5 t salt
•1 3/4 t pepper
•2 T minced garlic
•1/8 t ground cumin
1.Put all the ingredients in a crockpot and cook on high for about 8 hours.
2.After they are done, drain all of the liquid out and SAVE THE LIQUID!!
3.Mash beans with a potato masher or whatever you mash with. Add liquid, a bit at a time, to desired consistency, but remember you want them a little runny because they thicken over time. (makes about 6 cups)
