Instructions

Pick over beans. In a large bowl soak beans in cold water to cover by 2-inches for 1 day.

Drain beans and halve onion. In a 5 quart kettle simmer beans, lard or oil, onion, and epazote, if using, in water to cover by 2-inches, covered, 45 minutes, or until beans are almost tender. Add salt and simmer beans until just tender, about 15 minutes more. Beans may be prepared up to this point 2 days ahead and chilled in cooking liquid, covered. Drain beans in a colander.

Chop bacon and in a large heavy skillet cook over moderate heat, stirring, until browned. Add beans, salsa, beer, and salt to taste and cook, stirring, until most of liquid evaporates, about 10 minutes. Beans may be made 2 hours ahead and kept at cool room temperature. Reheat beans before serving.
