Soy-Marinated Flank Steak

We love flank steak in our house, especially with my signature teriyaki marinade found here.  But I was ready to try a new marinade for flank steak tonight and tried Martha Stewart's Soy-Marinade.  It was much less sweet than teriyaki and was very savory, especially the reduced sauce. It was fun to try something different, but I think my kids prefer the sweeter teriyaki marinade.

Flank Steak with Soy Marinade

1 cup soy sauce
1/4 cup packed light-brown sugar
3 tablespoons cider vinegar
1 tablespoon Worcestershire sauce
2 teaspoons Dijon mustard
1 teaspoon red-pepper flakes
2 garlic cloves, minced
1/4 teaspoon ground pepper
1 flank steak (about 2 pounds)

Combine marinade ingredients in gallon zip-lock bag. Add steak to marinade in bag and place in glass 9x13" pan. Marinade for at least 6 hours. Pull meat out of bag, reserving the marinade, and grill meat over medium heat for 8 minutes per side, or until the meat is cooked to your liking. Pour marinade from bag into saucepan and simmer over medium high heat for 10 minutes. The cooked marinade sauce is flavorful and very savory.  Enjoy!
