3/4 cup balsamic vinegar
3 tablespoons brown sugar
1 tablespoon mustard
1 tsp minced garlic
1/2 teaspoon kosher salt
1/2 teaspoon cracked black pepper
1 tsp orange zest
London Broil
Combine balsamic, brown sugar, mustard, garlic, salt, pepper, and orange zest in a bowl. Stir until sugar dissolves. Pour over meat. Marinate in fridge at least two hours turning meat occasionally.
Grill or broil. I broiled it for 15 minutes on each side. It was well done on the ends but still pink in the middle.
