In a large pan or Dutch oven, sauté the diced pork shoulder until browned.
Add chopped onion and minced garlic, cooking until softened.
Stir in cumin, oregano, smoked paprika, salt, and pepper.
Pour in orange juice and chicken broth, ensuring the pork is covered.
Bring to a simmer, then cover and let it cook for 2-3 hours until the pork is tender and easily shredded.
