The classic cochinita pibil is a traditional Mexican dish that originated in the Yucatan Peninsula. It is made with marinated pork, wrapped in banana leaves, and slow-cooked until tender. The marinade is a combination of citrus juices, achiote paste, garlic, and spices, which gives the dish its distinctive flavor. The pork is traditionally cooked in an underground pit, but it can also be prepared in a slow cooker or oven. The result is a flavorful and succulent dish that is perfect for tacos or served with rice and beans.
