From the following recipe from the Seoul Survivor Guide 2007-2008:
5 TBSP soy sauce
4 green onions, finely shredded
2 TBSP sake or dry white wine
3 TBSP sugar
3 large garlic cloves minced
dash of ground black pepper
2 TBSP sesame seeds
2 lbs thinly sliced pork or beef
1 TBSP sesame oil
Mix all the ingredients except the sesame seed oil. Add to sliced meat and marinate for at least 30 minutes. Add sesame oil just before grilling. Barbeque the meat slices over a charcoal grill or portable table top grill. Turn only once (thin slices cook quickly). A wok can be used if grill is not available. Serve over rice. We are using brown rice to make it healthier.
Koreans have propane table top grills. We used a grill plate that we bought here that goes over the burner on a stove. I used about half the sugar that the recipe calls for. We also added some spicy red bean paste as well.
