Wash beans thoroughly, and discard any bad ones or rocks! Place beans in pot and cover with water. Bring to the boil. Pour out water. Return beans to the pot and add fresh water to cover 2 to 8 cm (for thicker sauce use 5 cm). Add all other ingredients except salt. Bring to the boil again and reduce to simmer. If done in a crock pot it will take 8 to 10 hours. On the stove, it will take about 6 hours. Season with salt the last hour if needed, and continue cooking till done. Makes about 10 servings. Can freeze, and use later for frijoles refrito. Recipe By :
