Take out a large plastic container and make marinade. Start by adding: Water (4.5 cups), Soy Sauce (1/2 cup), Fish Sauce (4 Tablespoons), Mirim (1 Cup), Vinegar (1 Tablespoon), Sugar (2 Tablespoons) and Honey (2 Tablespoons). Give it a nice stir-around.
Now, carefully add-in the thinly sliced meat pieces into the marinade. Use your chopsticks to separate the pieces and make sure they don't clump up.
Then on the fresh ingredients: Slice an onion (1 whole) into thin slices. Add it to the marinade. Then julienne a carrot (1/2 a whole) into thin slices and add it to the marinade. Then mince 7 cloves of garlic and add it to the marinade.
Finish the marinade with Sesame Oil (3 Tablespoons), Sesame Seeds (2 Tablespoons) and Black Pepper (5-6 shakes) to the marinade.
Now the important part. Close the lid and place the plastic container in the refrigerator for a minimum of 5-6 hours. (If you have time, it's even better that you let it marinate overnight).
Optional: Take out a handful of Dangmyeon noodles and place into a bowl of cold water. Let it soak for at least 1 hour.
