Bulgogi is one of the classic Korean BBQ dishes. But it's also very useful for adding Korean beef to other dishes like bibimbap or making mashup dishes like Korean tacos and quesadillas. The secret to hand slicing the meat into paper-thin slices is to freeze it until semi-firm, about 3 hours. It will still be semi-pliable but very firm and easier to slice. You can also buy the beef pre-sliced at any Korean market. This marinade is also great for making a Korean style rib-eye, New York strip or filet mignon.
