Preparation Protocol
- Soak: Soak dry beans in water overnight, or at least 6 hours, then drain and rinse.
- Simmer: Combine soaked beans, onion, garlic, and bay leaf in a pot with fresh water to cover by 2 inches. Bring to a boil, then reduce to a low simmer.
- Cook: Simmer uncovered for 60-90 minutes, stirring occasionally, until beans are creamy and tender.
- Season and Finish: Remove the onion and bay leaf, stir in cumin, and season with salt to taste.
