Ingredients needed 🛒2 servings
- egg 4 pieces (about 200g)
- water 1 cup (200g)
- salt 1 pinch
- hondashi 1 pinch
- sugar 1 pinch
- baking powder 1 pinch
Recipe 🍳
- In a bowl, add 1 cup (200g) of water and crack in 4 eggs.
- Add salt, hondashi, sugar, and baking powder, each about a pinch, and mix well.
- Strain the egg mixture through a sieve once or twice to remove any stringy bits and shell fragments.
- Pour the egg mixture into a clay pot and heat over high heat initially.
- When bubbles start forming around the edges and cooking begins, gently stir to prevent burning at the bottom.
- Reduce heat to low when the egg is about halfway cooked and becomes soft and slightly firm.
- Cover with another clay pot of the same size or a lid that doesn’t let steam escape.
- After steam starts escaping between the pots, continue cooking for 1 more minute to finish.
- Mix water, eggs, seasonings, and baking powder to make the egg mixture.
- Strain the egg mixture and pour into a clay pot; bring to a boil over high heat.
- Once the egg starts cooking, stir gently, then reduce heat and cover with a lid.
- Turn off the heat after steam begins to rise, and serve immediately.
Cooking tips 💡
- Adding just a pinch of baking powder makes the custard puff up dramatically, especially if chilled before cooking.
- Straining the egg mixture removes strings and results in a much smoother texture.
- Lowering the heat when the egg is about half-cooked prevents scorching at the bottom.
- Placing another clay pot of the same size on top traps steam and helps the custard rise evenly from the top down.
- For extra flavor, garnish with roe, cheese, sesame oil, or red pepper flakes according to taste.
