Refried Beans Without the Refry

From allrecipes.com, by CHEFCLAUDE

• 1 onion, peeled and halved
• 3 cups dry pinto beans, rinsed
• 1/2 fresh jalapeno pepper, seeded and chopped
• 2 tablespoons minced garlic
• 5 teaspoons salt
• 1 3/4 teaspoons fresh ground black pepper
• 1/8 teaspoon ground cumin, optional
• 9 cups water

1. Place the onion, rinsed beans, jalapeno, garlic, salt, pepper, and cumin into a slow cooker. Pour in the water and stir to combine. Cook on High for 8 hours, adding more water as needed. Note: if more than 1 cup of water has evaporated during cooking, then the temperature is too high.
2. Once the beans have cooked, strain them, and reserve the liquid. Mash the beans with a potato masher, adding the reserved water as needed to attain desired consistency.
