Carne Asada Tacos or Al Pastor Tacos
I have had great success preparing tacos this way. I bought this recipe from a taqueria owner (taco restaurant) in Mexico City. I am translating the directions. It can be used for beef, pork, or just about any other type of meat. The spice mix on this recipe gives meat a really excellent flavor.
You may also use pork loin or pork chops. This recipe works really well with almost any variety or cut of meat. Thinly cut steaks work best with the tacos.
If you want to blend the flavors even more, you can simmer the paste in a saucepan stirring constantly and allow to cool. Filter marinade through a fine strainer and rub on both sides of steak.
You can tinker with this recipe to make the marinade as strong or as weak as you wish. You can double up or cut the marinade ingredients in half or increase the amount of any particular herb or spice. I find that the flavor of the meat in this recipe is almost addicting and I always end up grilling about ten pounds of beef so I make extra marinade. The longer you marinade the meat, the better.
