Pork Carnitas

1. Cut pork into large chunks. Season generously with salt, pepper, cumin, and oregano. 2. In a large Dutch oven or heavy pot, combine pork, orange halves, onion, garlic, bay leaves, lard, and water. 3. Bring to a simmer over medium-high heat, then reduce heat to low, cover, and cook for 2-3 hours, or until pork is very tender. 4. Remove orange halves and bay leaves. Increase heat to medium-high and continue to cook, uncovered, stirring occasionally, until liquid evaporates and pork begins to fry in its own fat and turn golden brown and crispy. 5. Shred the pork with two forks. Serve hot with tortillas and desired toppings.
