Food Network teaches how to crush, slice and mince garlic. Peel off some of the papery skin from the garlic and then smash the head of garlic with the heel of your hand to loosen the cloves; if you only need a few cloves, leave the head intact and pull some off. Separate the cloves. To peel a clove, cut away the root end with your knife. Lay the flat side of the knife over the clove while holding the knife handle, then with the heel of your free hand carefully whack the knife against the garlic to separate the skin from the clove. To crush the peeled garlic, lay the flat side of the knife over the clove and smash it again. To slice peeled garlic, lay the clove flat on the cutting board and hold it with the fingertips of one hand, keeping them curled under. Using a rocking motion with the knife, make thin slices by moving the knife slowly across the clove. To mince peeled garlic, lay the flat side of a knife over the clove and smash it. Roughly chop the clove then move your free hand flat across the tip of the knife and use a rocking motion to chop the garlic until it’s finely minced.
Lay the flank steak in a large baking dish and pour the mojo over it. Wrap tightly in plastic wrap and refrigerate for 1 hour or up to 8 hours, so the flavors can sink into the meat. Don't marinate the steak for more than 8 hours though, or the fibers break down too much and the meat gets mushy.
Preheat an outdoor grill or a ridged grill pan over medium-high flame (you can also use a broiler). Brush the grates with a little oil to prevent the meat from sticking. Pull the steak out of the mojo marinade and season the steak on both sides with salt and pepper. Grill (or broil) the steak for 7 to 10 minutes per side, turning once, until medium-rare. Remove the steak to a cutting board and let it rest for 5 minutes to allow the juices to settle. Thinly slice the steak across the grain on a diagonal.
Warm the tortillas for 30 seconds on each side in a dry skillet or on the grill, until toasty and pliable.
To make the tacos, stack up 2 of the warm tortillas, lay about 4 ounces of beef down the center, and sprinkle with some lettuce, onion, and cheese. Top each taco with a spoonful of the Pico de Gallo salsa and garnish with lime wedges. Repeat with the remaining tortillas.
In a mortar and pestle or bowl, mash together the garlic, jalapeno, cilantro, salt, and pepper to make a paste. Put the paste in a glass jar or plastic container. Add the lime juice, orange juice, vinegar, and oil. Shake it up really well to combine. Use as a marinade for chicken or beef or as a table condiment.
Yield: approximately 1 1/4 cups
