Cuban black beans and rice is a deeply comforting dish built on a foundation of rich, savory flavors. The process begins by simmering dried black beans until just tender, creating a flavorful cooking liquid. A traditional sofrito of green bell peppers, onions, and garlic is cooked down with rendered salt pork, cumin, and fresh oregano to build a robust aromatic base. Long-grain white rice and the cooked beans are then combined with the sofrito and baked until perfectly fluffy. A splash of red wine vinegar adds a bright finish to balance the richness. Serve it as a hearty side or a satisfying main course topped with fresh scallions.
