REFRITOS

Carefully sort out rocks and dirt balls. Wash and then put in large pot and fill 2/3 with water, beans will more than double in size. Let soak for 3 hours.

Add spices: (while they are soaking)

Cook:

Bring to a boil until beans expand a little bit aprox. 1/2 hr. then turn down flame and keep at a soft boil, adding water to keep the beans just barely covered with water. stir frequently( every 15-20 min). The beans are done when they are completely soft and the excess water is gone. Stir them briskly with a large spoon in order to get the right consistency, which is not really smooth but still has evidence of bean shapes.
