Step 1

Place beans in a large pot or dutch oven and add water until beans are submerged by 3 to 4 inches. Add the garlic and onion, squeeze in orange juice, then add the squeezed orange halves. Cover and place over high heat until water comes to a boil, then uncover pot and reduce heat to a bare simmer. Cook until beans are completely tender and creamy, 1 to 2 hours, stirring occasionally, and adding water if tops of beans become exposed.

Step 2

Remove orange and onion halves. Increase heat to medium and simmer, stirring frequently, until reduced to a thick, creamy sauce that clings to the beans, about 10 minutes. Season to taste with salt. Serve over rice or as a side with fresh cilantro and a dash or two of hot sauce.
