Prep: 15 minutes Marinate: 2 hoursGrill: 17 minutes
Trim fat from steak, and score in a diamond pattern. Place in plastic bag.In a blender combine cilantro, orange juice, vinegar, olive oil, garlic, cumin, coriander, chile peppers, kosher salt and black pepper. Cover and blend until smooth. Wear rubber or plastic gloves because chili peppers can irritate.Pour orange juice mixture into bag. Let marinate.Drain steak, discarding marinade. For a charcoal grill, place steak on the rack of an uncovered grill directly over medium coals. Grill for 17 to 21 minutes or until medium doneness (160°F), turning steak once halfway through grilling. Thinly slice against grain and plate.
Wine pairing: Zinfandel
Scoring the meat first allows excess fat to drain during cooking and assists with flavor absorption and tenderization while marinating. For less heat in the marinade, just use a couple teaspoons of the adobo sauce and leave out the chipotle peppers.
