To make these Perfect Pork Carnitas, start by turning the Instant Pot on to the sauté setting.
Add the avocado oil to the Instant Pot and allow it to heat.
While the pot is heating, prepare the pork shoulder by trimming away the fat and cutting it into cubes, approximately 3-inches in size (tip: you can also ask your buter to do this for you and skip this step!)
Once the pot is hot, add the pork shoulder to it and allow it to cook evenly, for 5-6 minutes. You may need to work in batches to ensure that the pork cooks evenly.
Once the meat has browned, add in the chicken broth, orange juice, lime juice, garlic, dried oregano, chili powder, ground cumin, kosher salt, and ground black pepper. Stir until the meat is fully coated in the seasonings.
Then, place the cover on the Instant Pot. Turn the settings on to "Manual Pressure," set to "high," and cook for 30 minutes with quick release.
Once the pork has finished cooking, remove it from the Instant Pot and transfer it to a baking sheet.
Shred the meat with two forks.
Then, turn your oven on to broil high and transfer the meat to the oven.
Allow the carnitas to broil for approximately 3 minutes, until the edges are browned and crispy.
Once they're done, remove them from the oven and prepare the tacos.
