Beans slowly simmered with pork bones until the broth becomes rich and flavorful. This protein-packed family dish extracts maximum flavor from humble ingredients in the Mexican tradition.
Rinse the dried pinto beans thoroughly and soak them overnight in water for optimal hydration and texture.
Drain soaked beans. In a large pot, add beans, pork neck bones, whole peeled onion, bay leaves, and garlic cloves. Cover with 8 cups of fresh water.
Bring the pot to a boil over high heat, then reduce to a gentle simmer. Skim away any foam or impurities that rise during the first 20 minutes.
Cover partially; simmer on low for 2 to 3 hours, stirring occasionally, until the beans are tender and the pork bones yield marrow and flavor to the broth.
Remove onion and bay leaves. Season the beans generously with kosher salt, black pepper, and ground cumin. Let simmer for an additional 10 minutes for seasoning absorption before serving.
