Savory Udon Egg Custard
4 servings
Ingredients
- 8 ounces cooked udon noodles
- 4 large eggs
- 2 cups cooled dashi or low-sodium stock
- 1 tablespoon low-sodium soy sauce
- 1 teaspoon mirin
- 4 shiitake mushrooms, thinly sliced

- 2 scallions, sliced
- 1 teaspoon toasted sesame oil
- Shichimi togarashi, optional
Step-by-step instructions
- Divide udon, shiitake, and edamame among four heatproof bowls.

- Pour custard over the noodles and cover each bowl loosely with foil.
- Set bowls in a wide pot on a folded towel. Add hot water halfway up the sides, cover, and steam over low heat for 18 to 24 minutes, until softly set with a slight wobble.
- Finish with scallions, sesame oil, and shichimi. Serve warm.
