At the new Mexicano market, El Mercado Fresca. Anyways.. I tried some of the Beef Shoulder Clod cut of meat. They are selling it cut thin, at a very cheap price $2.50. They even marinaded it free for me, in Mexican spices, onions and cilantro. I rushed home to try it for lunch. It is pretty good, and it was tender, not tough as I had expected. Not bad at all! They are like Steak Ums, but lots better. It is just the way they cut the Shoulder Clod into little steaks. It is called Bistec espaldilla de res. I bought some more up.
