Gavino's Recipe for "Chipotle-style Barbacoa" which is not authentic (doesn't use cheek meet).  Made entirely in instant pot; one dish meal!  I think it needs more spice than this to make it more savory, will report back next time I make it.

Start with:

2 Tbs (30g) Apple Cider Vinegar
¼ tsp Garlic powder
1 tsp Cumin
½ tsp Oregano
½ tsp Pepper
½ tsp Salt
add to 240 ml Hot Water
1 Tbs Lime Juice
3.5 oz can Chipotle (or less if you aren't spicy)
7g Better than Bouillon 

you could consider adding:
- splash of soy sauce
- shake of chipotle chili powder
- ½ tsp of paprika


Blend all of that until smooth.

take 2.5 lbs Chuck steak, cut into about 6 pieces.  Salt and pepper both sides, then, using avocado oil, sautee in instant pot to sear each side (probably in small batches to avoid crowding/allow it all to touch the hot surface).

finally, add all beef, the sauce and 1 Bay Leaf to instapot and pressure cook on high for 55 minutes, allow to rest for 20 minutes as pressure bleeds off, then shred with fork & eat!
