Ingredients
For hot spring eggs
- 5 egg
- scallions (optional, chopped for garnish)
For dashi sauce
- ½ cup dashi stock
- 1 teaspoon soy sauce
- ½ teaspoon salt
- ½ teaspoon cane sugar evaporated
Instructions
- Add 5 US cups of boiling water plus 1 ½ cups of room temperature water to a rice cooker.
- Add 5 eggs to the hot water and close the lid. Turn on the rice cooker's warming function and set a timer for 20 minutes.
- While you wait for the hot spring eggs to cook, add the ½ cup dashi stock, 1 teaspoon soy sauce, ½ teaspoon salt and ½ teaspoon evaporated cane sugar to a small saucepan and bring the mixture to a boil. Once the salt and sugar have dissolved, turn off the heat and let the sauce cool.
- Once the timer goes off, transfer the eggs to a cold water bath to stop the cooking.
- Crack the chilled eggs on a flat surface and gently break the Onsen Tamago into a small bowl. Serve drizzled with a small amount of dashi sauce and garnish with scallions.
