Flank steak in soy marinade

Ingredients:

• 1 flank steak weighing approximately 700 g.
• 1/3 cup soy sauce
• 3 tablespoons Worcestershire sauce
• 1 tbsp balsamic vinegar
• 2 tablespoons of vegetable oil
• 4 cloves garlic, crushed
• 1 teaspoon of sugar

Preparation:

1. Pierce the steak all over with the tines of a fork; cut in half across the grain to make two steaks (one may be slightly thicker than the other). In a non-reactive bowl or large zip-lock bag, combine the soy sauce, Worcestershire sauce, vinegar, vegetable oil, garlic, sugar, and black pepper to taste.
2. Add the steak and turn to coat with the marinade. Cover or seal the bag and marinate at room temperature for 1 hour or refrigerate for up to 6 hours.
3. Remove the steak from the marinade and pat dry with paper towels.
4. Position a rack in the upper third of the oven and preheat the oven to broil. Remove the steaks from the marinade and pat dry. Grill the steaks for 5-8 minutes per side until medium-rare. Transfer to a cutting board and let rest for 5 minutes.
5. Slice the steak diagonally across the grain into very thin slices. Arrange the slices on a warmed platter or plates. Serve.
