Coffee Marinated Steak - cooking recipe

Ingredients

2 tablespoons sesame seeds
6 tablespoons butter
1 medium onion, chopped
4 garlic cloves, minced
1 cup brewed coffee (strong)
1 cup soy sauce
2 tablespoons white vinegar
2 tablespoons Worcestershire sauce
2 lbs boneless beef top sirloin steaks (1 inch thick)

Preparation

In a small skillet, toast sesame seeds in butter. Add onion and garlic; saute until tender. In a large bowl, combine the coffee, soy sauce, vinegar, Worcestershire sauce and sesame seed mixture.
Pour all into a large resealable plastic bag; add steak. Seal bag and turn to coat; refrigerate for 8 hours or overnight, turning occasionally.
Drain and discard marinade from steak. Grill steak, covered, over medium-hot heat for 6-10 minutes on each side or until meat reaches desired doneness (for medium-rare, a meat thermometer should read 145\u00b0; medium, 160\u00b0; well-done, 170\u00b0). Enjoy the steak.
