This recipe was adapted from a gourmet and international recipe website. The flavors sound wonderful and I will be making this soon. The african recipe can also be found in the Zaar World Tour 2005 swap.
Combine all ingredients, except steak, in a jumbo ziplock bag that has been placed in a glass bowl for support. After scoring the flank steak place it in the bag. Seal the bag and refrigerate at least 20 minutes or up to overnight.
Heat the grill or a grill pan on the stove. Remove the flank steak from the bag and pat dry with paper towels. Grill 4 to 5 minutes per side or until done to taste. Let rest 5 to 10 minutes before carving before serving.
