I do something similar with cumin, garlic, Mexican oregano, chipotles, bay leaves, and a little tomato paste, but I also like to put some smoke on the meat beforehand.Nicely done
I buy the beef cheek, throw it in the crock pot at night with cilantro, onion, and tomato and leave it on overnight.
In the morning, barbacoa.
Just gotta squish some avocado and heat up some tortillas. I prefer corn tortillas with barbacoa.
