Carne asada is a big time favorite of mine and it is very easy to make. Carne Asada Several pounds of Skirt or Flank steak marinated over night in a tasty marinade of citrus juice, soy sauce, fresh garlic and various other ingredients. The citrus, soy, salt and garlic are the basics of any carne asada marinade. Those four alone can deliver up a delicious pile of Carne Asada. Lime, lemon, sour orange, orange and pineapple are the most commonly used citrus juices. Amazing natural tenderizers. I prefer my juices fresh with plenty of pulp if possible. ***To mimic Sour Oranges for this or other Mexican recipes such as Carnitas or Puerco Pibil, just mix 1:1:1:1 Grapefruit, Orange, Lime juices and vinegar.*** Believe it or not but soy sauce is found in many a Mexican kitchen, and is almost always used in a carne asada marinade. It is a key ingredient for the Umami flavor it adds to the beef. I also often add a splash of fish sauce. Salt, the one spice that can bring out the most flavor in almost anything. Another natural tenderizer. And without it, we die. And garlic, what can one say, garlic is one of the many gifts from the Garden of Eden. This wonderfully pungent, spicy and flavorful bulb is world renowned in cooking. Other herbs/spices. Don't be afraid to let your inner chemist out. Chiles, pepper, cumin, cloves, allspice, coriander seed, Mexican oregano, cilantro and more. I don't think any two of my carne asada marinades are ever exactly the same. Sure, I've a basic recipe written down but I usually measure by eye and freely substitute and/or add according to what I have on hand and how spicy I want it. I just make sure I've enough to cover my meat in the bag or bowl.
