This recipe was shared with me by a mother at my son's school (Shirley Brothwell). She says: "My mother learned this dish when we lived in South Korea"

Ingredients Nutrition


  1. Score the flank steak the diagonally on both sides. Cut the steak across the grain (this is also usually on the diagonal) into strips about 3 inches wide. Once all tenderizing cuts have been made, cut into serving sized pieces still large enough to grill.
  2. Mix vegetable oil and sugar together in gallon sized Ziplok bag. Add flank steak and soak for 20 minutes (this tenderizes the meat).
  3. Meanwhile mix remaining ingredients as marinade. Add mix to steak in bag and refrigerate for 4 hours, turning occassionally. Grill over hot fire about 2 minutes per side.

We really enjoyed this steak. I did, however, just throw everything into the ziplock at once and let it marinate all day. It worked great. Thanks for posting! Made for PAC Spring 2009.

I was really hoping that my kids wouldn't like this, but they did. I had to fight them for the leftovers. This was sooo delicious, can't wait to make it again. I did however only put in half of the cayenne pepper, I don't like things too spicy. I also mixed all the ingredients together in one bowl and then added it to the meat. It marinated all day and it was perfect! Thanks for the recipe.
