Mix the spices and salt together. Toss spice mix with the pork .
Using the high sauté function on the instant pot, sear the sides of each piece of pork in the avocado oil. Work in batches. Remove pork and set aside.
Deglaze the instant pot with the beer and citrus juices.
Add the chicken broth and garlic cloves.
Return pork to the Instant Pot and cook on high pressure for 1 hour. Allow the pressure to release naturally.
After the pork has cooked, remove from the instant pot and shred the meat.
Turn the Instant Pot back onto the high sauté function to reduce the cooking liquid. Let this reduce while you crisp up the carnitas and prep the assembly.
Put the shredded meat onto a baking sheet and broil on high for just a few minutes to crisp up the edges of the pork.
Sweet Corn Salsa
Toss the corn, onion, cilantro, lime juice, salt, and jalapeño pepper in a bowl.
Test for salt. Add more if you would like.
Let the salsa hang out in the fridge while the pork cooks.
Assembly
Add crisped pork onto warmed corn tortillas. Top with corn salsa. Garnish with the Cotija and avocado. Dip into the reduced cooking liquid. Enjoy!
