1 tablespoon olive oil
1 small white onion, finely chopped
2 cloves garlic, finely chopped
2 jalapeño peppers, seeded and chopped
Salt and pepper
1 1/2 teaspoons ground cumin (half a palmful)
1/2 cup water
2 (14-ounce) cans black beans
Juice of 1 lime
1 tablespoon hot sauce (Rach’s go-to is Frank’s)
Heat olive oil, a turn of the pan, in a small saucepan over medium-high heat. Add onions and garlic, jalapeño, salt, pepper and cumin, and cook 5 minutes to soften. Add water and reduce to 2-3 tablespoons. Add beans and heat through.
Transfer beans to the bowl of a food processor and add lime juice and hot sauce. Process until smooth, adjust salt to taste.
