I used a pound of pinto beans and added about 5 or 6 cups of very hot water.
My rice cooker has different settings, so I used the brown rice setting. It cooked in about 1 1/2 hours. I checked on it every once in awhile and stirred it.
After they cooked, I let them sit in the warm cycle while I was cooking other things. Before cooking, I added a little bit of ground cumin and oregano and one beef bouillon cube. They turned out perfectly. I have been known to burn my beans in the past, but that will never happen again. When I was done with the beans, I removed them and cooked the rice. So easy, and my rice cooker has a non-stick insert so clean up was even easier. Loved it!
