- 4 pounds pork butt or pork shoulder (preferably Berkshire pork), trimmed, cut into 3x3-inch chunks
- 10 1/4 cups peanut oil, divided
- 2 1/2 cups cola-flavored soda, divided
Sprinkle pork with salt and pepper. Heat 1/4 cup peanut oil in heavy 8-quart pot over high heat. Working in batches, add pork to pot and sauté until browned on all sides, about 7 minutes per batch. Using slotted spoon, transfer pork to large bowl.
Pour remaining 10 cups peanut oil into same pot. Attach deep-fry thermometer to side of pot; heat over medium heat until thermometer registers 280°F. Add pork to oil in pot (temperature of oil will drop to between 180°F and 200°F). Cook pork over medium heat until brown and tender, adjusting heat as necessary to maintain temperature of oil between 200°F and 220°F, about 1 1/2 hours. Using slotted spoon, transfer pork to another large pot. Add orange juice and 2 cups cola to pork and bring to boil; reduce heat and simmer until pork is very tender, about 35 minutes. Add remaining 1/2 cup cola and stir over medium heat until meat falls apart and liquid is absorbed, about 5 minutes longer. Season generously with salt and pepper. Transfer to bowl and serve.
