I made this the other day and it was a big hit. It was the first time I had made it, but it will become part of my regular repertoire.
London Broil with Steak Sauce Gravy
1 1/2 pounds shoulder London broil steak, 1 1/2 inches thick
1 tablespoon Worcestershire sauce
1 shallot, finely chopped
2 tablespoons all-purpose flour
2 cups beef broth
1/4 cup steak sauce
Turn broiler on. Brush meat with Worcestershire and season with salt and pepper. Cook London broil on top rack for 7-8 minutes on each side.
Place a small skillet over medium heat. Melt remaining 2 tablespoons butter, add finely chopped shallot, cook 2 minutes, then whisk in flour and cook 1 minute. Add 2 cups beef broth to the pan and bring to a bubble. Reduce the broth 2 minutes then add 1/4 cup steak sauce and black pepper, to taste.
