3 cups dried navy or pinto beans
3 tsp. dried cumin
3 tsp. chili powder
3 T. dried minced onion
In a coffee grinder, food mill or blender, grind beans until a flour consistency. Combine all ingredients and store jar or ziploc bag.
3/4 cup mix
2-1/2 cups boiling water
Mix with a wire whisk until combined. Bring to boil, cover, reduce heat to low and simmer for 4-5 minutes or until thickened. Mixture will thicken more as it cools. Refried beans will remain thickened even when reheating. You can add salsa or chopped chili peppers for added zip.
