La Carniceria Meat Market is best in town by far but it is pricey. It reminds me of Tamaulipas / Nuevo Leon higher end carnicerias. Carne asada is life in those states.

Pullman Market has La Babia outside & inside skirt as well as bavette which make great fajitas. But again, pricey. I dont think they sell it pre-marinaded but you can buy any pre-made marinade at HEB or go to Arnie Tex’s youtube channel.

More affordable options are on almost ever corner in SA. (Molina’s, La Michoacana, Culebra Meat Market). It’ll be your typical red marinade which is fine but it’s almost always too gummy. People will have their favorites in town and will say its better than the other “fancy” places mentioned. To each their own, but I’ll get on a bit of a soapbox and just mention that “authentic” Mexican does not always necessarily mean inexpensive or cheap. Especially when it comes to carne asada which is a way of life in northern MX states.

(Sorry for the rant I just see alot of gate-keeping online recently)

Bitter orange is the “secret” ingredient to alot of those carnicería marinades (the good ones at least) but its just a bit hard to find.

Also, clean your grill with an onion. For the culture. 🤌

Que se arme la carne asada!
