Skirt steaks cook in a flash—less than 8 or 10 minutes—but should be marinated first in a brew bolstered by a flavorful acidic ingredient such as the pomegranate juice used here, fortified by the molasses. Although skirt steaks are relatively inexpensive, it's a good idea to buy USDA Prime or Wagyu steaks and pay close attention when you grill them. This way you will be guaranteed tender, absolutely delicious meat.
Pomegranate juice is sold in most supermarkets in the produce section alongside fresh orange juice, apple cider, and other fresh juices. It requires refrigeration.
