Prepare the egg in advance and let it rest in the marinade for several hours, or ideally overnight, to achieve a rich, intense flavour.
step
Heat water in a pot and cook the egg for 3-5 minutes, then cool it in cold water. Peel the egg and marinate it in 4 tbsp soy sauce (for a more intense flavour, marinate the egg longer).
Cut the stems of the choy sum into small pieces, and slice the leaves more generously.
Peel and finely chop the garlic, slice the green onions, and trim the root ends off the enoki mushrooms.
Season the beef with salt and pepper, then sear for 3-4 minutes on each side.
Add the enoki mushrooms along with soy sauce and 150 ml of water, stirring well. Bring 500 ml of water to a boil and cook the Demae Ramen noodles for 3 minutes, then remove from heat and add the seasoning powder and oil.
