Chawanmushi: Steamed Egg Custard
This is a quiet dish that relies on patience rather than complexity. When done properly, the custard should tremble slightly when touched, holding the flavor of the sea and the umami of the broth.
The temperature determines the texture.
Control your heat. If the water boils aggressively, the custard will become pockmarked with holes instead of remaining smooth.
- steamer pot
- fine-mesh sieve
- 4 small custard cups or tea bowls with lids
- aluminum foil (if lids are missing)
What goes in.
- 3 largeeggs
- 2 cupsdashi broth, cooled to room temperature
- 1 tbsplight soy sauce
- 1 tspmirin
- 4 smallshrimp, peeled and deveined
- 4shiitake mushroom slices
- 4mitsuba or scallion segments
Eliminating Bubbles
Pass the egg and dashi mixture through a fine-mesh sieve at least twice. This removes the chalaza and any trapped air, ensuring the finished custard is uniform and glossy.
The method.
Prepare the egg base
Whisk the eggs gently in a bowl. Do not introduce foam. Stir in the dashi, soy sauce, and mirin.
Strain the mixture
Pour the liquid through a fine-mesh sieve into a measuring cup with a spout. Repeat this process until the liquid is perfectly smooth.
Arrange the vessels
Place the shrimp and mushrooms into the bottom of each custard cup. Pour the egg mixture over the ingredients until the cups are nearly full.
Steam with care
Place the cups in a steamer over medium-high heat. Once steam rises, turn the heat to the lowest setting possible. Cover and steam for 12 to 15 minutes.
Check for doneness
Gently shake a cup; the center should jiggle like gelatin. If it is liquid, steam for another minute.
Other turns to take.
Vegetarian
Substitute the dashi with a kombu-only broth and use ginkgo nuts or tofu cubes instead of shrimp.
Rich
Add a small piece of chicken thigh or clam meat to the bottom of the cup for extra depth.
When it doesn't go to plan.
Use room temperature ingredients so the custard sets evenly.
If your steamer lid drips, wrap it in a clean kitchen towel to prevent water from falling onto the custard surface.
Serve immediately while hot, but leave the lid on until the moment of serving to retain the aroma.
The ones that keep coming up.
Why did my custard turn out firm instead of soft?
The heat was likely too high. High heat overcooks the eggs and causes the proteins to tighten and expel liquid.
Can I make this ahead of time?
It is best prepared fresh. Chilled chawanmushi can be served, but it loses the signature ethereal quality.
