Beat the eggs gently in a medium bowl. Ensure that the eggs do not foam.

Mix chicken powder, dashi, soy sauce, salt, sugar, and water. Then, stir slowly until well combined.

Place mushrooms, shrimp, and crab sticks in a cup.

Pour the egg mixture into the cup while straining it until it's 3/4 full. Cover the cup with plastic wrap, then poke some holes in the top.

Heat the steamer until the steam rises. Reduce the heat, and place the cup into the steamer slowly. Cover the steamer, increase the heat again, and steam for 5-7 minutes. Then, reduce the heat and continue steaming for 10 minutes.

Serve while warm!
