2 tablespoons dark soy sauce
1 tablespoons light soy sauce
4 tablespoons sugar
8 spring onions, white and tender green parts only, coarsely chopped
1 tablespoon fresh ginger, peeled and grated
3 cloves garlic, minced
2 tablespoons cooking rice wine
5 tablespoons Sesame oil
1 kg really thinly sliced beef (available prepacked in the freezer section of good korean/asian groceries)
Mix all the ingredients thoroughly except the sliced beef.
Add the beef and marinate for about 1 hour.
Heat some cooking oil in a large frying pan or bbq plate (no oil required if using a non stick pan)
Put the sliced beef in a few at a time and sear on both sides for about 1 minute per side.
Leave it on a bit longer if you want the sugar to caramelise.
