Boil the tteok and drain. Finely chop the beef and vegetables. Separate the egg yolk from the egg white and make a finely shredded omelet.
Combine the beef and shiitake mushrooms with the "A" ingredients, and stir-fry. Add the tteok, carrot, green pepper, and onion, and continue stir-frying.
Add the dashi stock to Step 2 and cook over low heat while slowly stirring to combine. Add the leek and cook until the liquid evaporates. Turn off the heat and drizzle with sesame oil.
Transfer to a dish and top with the finely shredded omelet and nori.
Story Behind this Recipe
I learned this from a Korean instructor.
If you finely chop the tteok, the flavor will bind better. Adding a small amount of grated garlic to the Japanese leek in Step 3 enhances the flavors. Cut the thin omelet into diamonds to make it resemble the dish served at the Imperial Court.
