Korean Beef

With a sharp knife, thinly slice the steak against the grain at a 45-degree angle. This ensures the steak will be tender. (Youtube videos like this one are helpful if you've never done it before.) In a food processor (a small one will do the job), process the soy sauce, green onions, garlic, toasted sesame oil, brown sugar and cayenne until smooth. In a bowl, combine the steak with the marinade, stirring until the steak is evenly covered. Refrigerate for at least two hours up to overnight. Prepare a hot grill. Fold or "ribbon" the steaks onto the skewers. Grill the steaks for 4 minutes, flip them and cook for an additional 4-5 minutes until they're cooked to your liking. Our preference is medium rare. Garnish with sesame seeds.
