Ingredients

Egg Filling

  • 4 large eggs (soft boiled)
  • 4 tablespoons mayonnaise (Japanese mayo preferred)
  • 1 teaspoon soy sauce (optional)
  • 1 teaspoon salt (to taste)
  • 1 teaspoon black pepper (to taste)

Sandwich

  • 8 slices white bread (or soft sandwich bread)
  • 1 tablespoon butter (for spreading)

Instructions

  1. Prepare the Egg Filling: Boil the eggs in a pot of water for about 6-7 minutes until they are soft-boiled with slightly runny yolks.
  2. Cool the Eggs: Once cooked, immediately transfer the eggs to an ice bath to stop cooking and make peeling easier.
  3. Peel and Chop: Peel the cooled eggs carefully and chop them into small pieces for the filling.
  4. Mix the Filling: In a mixing bowl, combine the chopped eggs with mayonnaise, soy sauce, salt, and black pepper. Mix everything until well blended and creamy.
  5. Butter the Bread: Spread butter evenly on one side of each slice of bread to ensure a golden, flavorful crust once toasted.
  6. Assemble the Sandwich: Place a generous amount of the egg filling on the unbuttered side of half the bread slices.
  7. Complete the Sandwiches: Top each with the remaining bread slices, with the buttered side facing outward.
  8. Toast the Sandwiches: Heat a pan over medium heat and toast the sandwiches until golden brown and crisp on both sides, usually about 2-3 minutes per side.
  9. Serve: Cut the sandwiches diagonally for easy handling and enjoy immediately while warm.

Notes

  • Soft boiling the eggs for 6-7 minutes ensures a creamy yolk but slightly firmer than raw.
  • Japanese mayonnaise adds a richer, sweeter flavor compared to regular mayonnaise.
  • Soy sauce is optional but adds a subtle umami depth to the filling.
  • Use soft sandwich bread or milk bread for the authentic fluffy texture.
  • Butter the bread well for a golden, crisp outer layer when pan-toasting.
  • Serve immediately for the best taste and texture; the bread will soften if left too long.
