Cut pork shoulder into 1" cubes
In a large dutch oven, heat vegetable oil on medium high heat and pre-heat the oven to 350° F.
Add pork into the pork to pan fry, careful to not overcrowd the pot or pork pieces will not brown.
Once all pork is browned, place all the pork, onions, bay leaves, oregano, salt, pepper, orange juice, and garlic.
Combine hot water and then milk to the pot. ** If you add the milk first it may curdle due to the hot temperature.
Cover and roast in the oven for 3-4 hours or fork tender.
