Not a problem.. I scoured recipes to find anything close to what I used to cook at the restaurant.
Bulgogi (Korean Barbecued Beef) - Allrecipes
I generally freeze the sirloin for about an hour ahead of time and slice it nice and thin. Then I marinade. I do use MSG.
From there, I pan fry the entire contents (Marinade and all) until the sirloin is cooked. For me, I then follow through with putting it either over an open flame (Grill) or use a grill pan. For me, it's all about a little blackened parts.. Flame kissed if you will...
Anyways, it's AWESOME!
