Servings 4 servings (one ramekin each)

Equipment

  • Steamer or Deep Saucepan: With a lid (a bamboo steamer works great, too)
  • Heatproof Ramekins or Small Cups: 4 individual servings (about 4–6 oz each)
  • Mixing Bowl: For combining the egg mixture
  • Whisk or Chopsticks: To gently beat the eggs
  • Fine Mesh Strainer: For ensuring an ultra-smooth custard
  • Ladle: For portioning the mixture into cups
  • Aluminum Foil or Lids: To cover the cups during steaming

Ingredients
  

  • For the Egg Custard Mixture:
  • 4 large eggs
  • Use at room temperature for a smoother blend
  • 2 cups dashi stock
  • Preferably freshly made from kombu and bonito flakes, or a high-quality instant dashi
  • ½ teaspoon salt
  • 1 teaspoon soy sauce
  • ½ teaspoon mirin
  • Optional Add-Ins Arrange one or a combination in each cup:
  • 4 small shrimp: Peeled deveined, and lightly scored
  • ½ cup chicken thigh: Cooked and cut into bite-sized pieces
  • 2 shiitake mushrooms: Stems removed caps sliced thinly
  • A few slices of kamaboko fish cake
  • A small handful of enoki mushrooms: Trimmed
  • A few ginkgo nuts or other seasonal vegetables
  • Tip: Feel free to substitute or add any ingredients you enjoy—traditional choices vary by region and season.

Instructions
 

  • Prepare the Custard Mixture:
  • In a large bowl, gently beat the eggs with a whisk or chopsticks. Avoid creating bubbles.
  • Add the dashi, salt, soy sauce, and mirin. Stir very gently until fully incorporated.
  • Strain the mixture through a fine mesh strainer into a clean bowl to remove any chalazae or unmixed egg, ensuring an ultra-smooth texture.
  • Set Up the Cups:
  • Lightly prepare your ramekins by placing your chosen add-ins (shrimp, chicken, mushrooms, etc.) evenly in the bottom of each cup.
  • Slowly pour the strained egg mixture over the add-ins, filling each cup nearly to the rim (leave a little room for expansion).
  • Cover and Steam:
  • Cover each cup tightly with a piece of aluminum foil (or use a lid if your cups have one) to prevent water droplets from disrupting the custard’s smooth surface.
  • Preheat your steamer or saucepan with about 1–2 inches of water. Ensure the water is at a gentle simmer; high heat can cause bubbles.
  • Carefully place the cups in the steamer basket. Steam over low heat for approximately 15–20 minutes. (Cooking time may vary slightly depending on cup size and the strength of your heat source.)
  • Check doneness by inserting a toothpick or a skewer into the center—it should come out clean, and the custard should be just set with a slight wobble in the middle.
  • Finish and Serve:
  • Once done, remove the cups from the steamer. Allow them to rest for a couple of minutes.
  • Optionally, garnish with a few finely chopped mitsuba leaves or a sprinkle of chopped green onions.
  • Serve warm as an elegant starter or a light main course.

Notes

Gentle Whisking: Beat the eggs gently to avoid incorporating too much air, which can create bubbles in the custard.
Straining is Key: Straining the egg mixture ensures a silky texture, free from chalazae or clumps.
Steaming Temperature: Use low heat during steaming to prevent rapid boiling, which can cause uneven setting or bubbly texture.
Customizable: Experiment with different add-ins—seasonal vegetables, seafood, or even tofu—for a personal touch.
Timing: Adjust the steaming time if using larger or deeper cups; always check for a clean toothpick test in the center.
Dashi Quality: High-quality dashi significantly enhances the flavor profile, so opt for homemade if possible.
