2 cloves garlic, minced
1/4 cup white vinegar
2 tablespoons canola oil
2 teaspoons ground ancho chile pepper (see Ingredient note)
1 teaspoon dried oregano
1 teaspoon ground cumin
1/4 teaspoon salt
1 1/4 pounds flank steak, trimmed of fat
1. Whisk garlic, vinegar, oil, ground chile, oregano, cumin and salt in a small bowl. Place steak in a shallow baking dish and pour marinade over it, turning to coat both sides. Cover and refrigerate for at least 1 hour, turning once, or overnight.
2. Preheat grill to high heat. Oil the grill rack (see Tip). Grill the steak until desired doneness, 5 to 6 minutes per side for medium. Transfer to a plate, cover with foil and let rest for 5 minutes. Slice the steak very thinly across the grain. Serve warm or chilled.
To oil a grill: Oil a folded paper towel, hold it with tongs and rub it over the rack. (Do not use cooking spray on a hot grill.) When grilling delicate foods like tofu and fish, it is helpful to spray the food with cooking spray.
Ingredient note: Ancho chile peppers, one of the most popular dried chiles used in Mexico, are dried poblano peppers. They have a mild, sweet, spicy flavor. Ground ancho chile pepper can be found in the specialty-spice section of large supermarkets, or substitute ground chili powder with a pinch of cayenne.
