- 1/4 lb dried black beans (2/3 cup), picked over and rinsed
- 1 small onion, finely chopped (1/2 cup)
- 2 fresh cilantro sprigs
- 1/2 tablespoon olive oil
- 6 cups cold water
- 1/4 teaspoon salt, or to taste
- Bring beans, onion, cilantro sprigs, oil, and water to a boil in a 2-quart heavy pot. Reduce heat and simmer, partially covered, until beans are just tender, about 1 1/4 hours. Add salt and simmer, uncovered, until liquid is evaporated to just below level of beans. Season with salt and discard cilantro sprigs.
