Ingredients

4 large eggs

4 tablespoons Japanese mayonnaise (e.g., Kewpie)

1 teaspoon sugar

1/4 teaspoon salt

2 slices soft white bread (crusts removed)

Instructions

Boil the Eggs:
Place eggs in a pot of cold water. Bring to a boil and cook for 10–12 minutes until hard-boiled. Transfer to an ice water bath to cool.

Make the Egg Filling:
Peel the cooled eggs and mash them in a bowl using a fork or potato masher. Add Japanese mayo, sugar, and salt. Mix until smooth and creamy.

Assemble the Sandwich:
Spread the egg mixture thickly on one slice of the crustless bread. Top with the second slice and press gently to seal.

Slice and Serve:
Cut the sandwich into halves or quarters for a traditional Japanese presentation. Serve immediately or wrap and refrigerate for later.

Notes

Bread Tip: Use shokupan (Japanese milk bread) or any super soft white bread for an authentic texture.

Customize: Add finely chopped chives, a dash of mustard, or even an extra yolk for a richer filling.

Make-Ahead: Wrap in plastic and refrigerate up to 24 hours. Best served slightly chilled or at room temp.
