• Combine all the carnitas rub ingredients in a mortar and pestle and grind until powdered.

Prep for all cooking methods

• Cut the pork into 3-4 inch pieces.
• Rub the dry rub on all sides of the pork. If you have any spice rub left, add it to the pork once in the pot, before cooking.

Instant Pot carnitas

• Turn the Instant Pot to sauté and add the olive oil.
• Brown the pork on all sides.  Work in batches if needed - don't crowd the pot during browning.  When each batch is browned on all sides, set aside until all pieces are browned.
• Add broth, orange and lime juices and deglaze the pot, scraping as many cooked bits from the bottom of the pot as possible.
• Place the pork in the Instant Pot and top with the deglazing liquid, onion and garlic and any leftover spice rub.
• Cook on the "Meat" setting for 60 minutes (15 min/lb) and use the natural release method.

Carnitas in the slow cooker

• Pre-heat the slow cooker on high.
• Add the olive oil to a skillet and brown the pork on all sides on medium heat and set aside on a plate.
• Add the broth, lime and orange juices and deglaze the skillet.
• Add the pan juices, browned pork, onion and garlic and leftover spice rub to the slow cooker and cover.  Turn to low and cook for 8-10 hours.

Carnitas in the oven

• Pre-heat the oven to 300 °F degrees.
• In a large oven-safe pot or Dutch oven, heat the olive oil at medium heat on the stovetop.
• Add the pork and brown on all sides, then set aside on a plate.
• Add the broth, lime and orange juices and deglaze the pot.  
• Add the pan juices, pork, onion, garlic and any leftover spice rub to the pot and cover.  Bake in the oven for about 3 ½ hours until the meat is tender and shreddable.

Shred the pork

• With two forks, pull the meat into shreds.

To crisp the carnitas

• Crisp in a skillet - carefully remove the shredded pork from the pot juices and place in the skillet.  Cook on medium heat until crisp, flipping often, about 5-10 minutes.
• Crisp in the oven - pre-heat to 450 °F.  Place the shredded carnitas on a sheet pan and bake until crisp, about 20 minutes.
• Crisp by broiler - Place the shredded carnitas on a sheet pan and broil for about 5-10 minutes, turning them over about half-way through.
