Prep: 10 mins
| Cook: 10 mins
| Extra time: 4 hours, marinating
1.
Combine all ingredients in large plastic resealable bag, turn to coat, and place in refrigerator to marinate for 4 hours.
2.
Heat your gas or charcoal grill to high (Here's how to tell if it's high: Hold your hand about four inches above the cooking surface. After 2 to 3 seconds, the heat will force you to pull your hand away.)
3.
Oil the grill grate, using an oiled rag.
4.
Remove steak from marinade and place on the grill. Use these cooking times to cook your steak to medium: 2 to 3 minutes per side for a 1/2 inch thick steak, 4 to 6 minutes per side for a 1 inch thick steak, 6 to 9 minutes per side for a 1 1/2 to 2 inch thick steak.
5.
Take the steak off the grill. Let it rest 2 to 3 minutes to allow the juices to reabsorb into the steak. Serve.
Note
Recipe makes about 3 cups of marinade, enough for 6 pounds of steak.
Awesome! One of the best marinades I've come across for flank steak, and very easy to throw together. The stout combined with the other ingredients gives it a nice bold flavor.
