Tex-Mex Flank Steak - cooking recipe

Ingredients

4 tablespoons tomato paste
1 cup black coffee, strong
1/4 cup Worcestershire sauce
1 tablespoon sugar
1 tablespoon salt
1 teaspoon cayenne pepper
1 teaspoon black pepper
2 tablespoons fresh lime juice
1/4 cup vegetable oil
1 (3 lb) flank steaks

Preparation

Mix all ingredients except steak and heat in a medium saucepan, stirring until sugar melts and flavors are combined.
Marinate meat in the sauce for 4-5 hours or overnight in the refrigerator, turning occasionally.
Remove meat from the marinade, heat and use as a baste or sauce if you like, and sear meat quickly over high heat, about 1 minute per side, and then lower heat to medium-low and continue cooking about another 5 minutes per side until done to your liking.
Slice meat on a diagonal against the grain into thin slices.
