skirt steak with cilantro garlic sauce

i made this a few weeks ago and it was great.

For sauce

* 1 medium garlic clove
* 1/2 teaspoon salt
* 1 cup coarsely chopped fresh cilantro
* 1/4 cup olive oil
* 2 tablespoons fresh lemon juice
* 1/8 teaspoon cayenne


For steak

* 1 teaspoon ground cumin
* 1/2 teaspoon salt
* 1/2 teaspoon black pepper
* 2 pound skirt steak, cut crosswise into 3- to 4-inch pieces

Preparation

Make sauce:
Mince garlic and mash to a paste with salt. Transfer to a blender and add remaining sauce ingredients, then blend until smooth.

Grill steak:
Stir together cumin, salt, and pepper in a small bowl. Pat steak dry, then rub both sides of pieces with cumin mixture.

Heat an oiled well-seasoned ridged grill pan over high heat until hot but not smoking, then grill steak in 2 batches, turning over occasionally, about 2 minutes per batch for thin pieces or 6 to 8 minutes per batch for thicker pieces (medium-rare). Serve steak drizzled with sauce.
