Carne Asada - The Real Deal - cooking recipe

Ingredients

2 lbs flank steaks (preferably flap meat from Mexican grocery)
3/4 cup beer (6 oz)
1 teaspoon dried oregano
1/2 teaspoon ground cumin
1/2 teaspoon achiote powder (optional)
1/4 cup orange juice
1 teaspoon sugar
3 garlic cloves, minced
salt
pepper
1 pinch red pepper flakes (optional)

Preparation

In a large ziploc bag, place beer, oregano (rub between palms to crush while adding), cumin, orange juice, sugar and garlic. Add salt and pepper to taste, making it a bit on the salty side.
Add red pepper flakes and achiote powder, if using. Achiote gives it a nice color and a subtle taste.
Zip bag closed and shake or knead to blend all ingredients well.
Add flank steak, zip closed and combine to saturate all sides of beef. Refrigerate at least one hour, turning and shaking bag from time to time.
Drink rest of beer while meat is marinating.
Place meat on hot grill, turning only once, about four minutes per side for medium well.
When done to your liking, place meat on cutting board, let rest for a few minutes, then cut into small 1/2 inch pieces.
Serve with warm corn and/or flour tortillas, guacamole, salsa and sour cream (or crema fresca). Beans and mexican rice on the side - see my recipe for the rice.
