Bourbon London Broil with Sweet Heat

1 1/2 London Broil steak

1/2 cup brown sugar

1/4 cup honey

1/2 cup soy sauce

1 tsp red pepper flakes

2 Tbsp bourbon

2 garlic cloves 

In a medium mixing bowl, whisk together brown sugar, honey, soy sauce, red pepper flakes, bourbon, and garlic until sugar has dissolved.  Pour mixture into a zipper-locking plastic bag with beef.  Refrigerate overnight.  

Preheat oven to broil.  Remove the beef from the marinade; reserve remaining marinade.  

Pat dry and place on broiler pan.  Broil for 4 - 5 minutes.  Flip and broil an additional 4 - 5 minutes.

In a small saucepan, over medium-high heat bring reserved marinade to a boil.  Reduce heat to low; simmer 10 minutes while beef rests on a cutting board.  Slice thinly against the grain and serve covered with warm sauce.
