Recipe

Place the eggs in a pot, hard-boil them, then cool in cold water, peel, and separate the whites and yolks.
Finely chop the egg whites with a knife.
In a bowl, combine the yolks with 1/2 tbsp sugar, 1 pinch salt, and a little pepper, mash, then gradually add milk while stirring to achieve a moist consistency.
Add mayonnaise to the yolks and mix well to create a smooth, creamy texture.
Add the chopped egg whites to the creamy yolk mixture and mix evenly to complete the egg mayo filling.
Spread whole-grain mustard and the egg mayo filling evenly between the slices of bread.
Trim the crusts, cut into bite-sized pieces, and arrange on a plate.

Chop the boiled egg whites; mix the yolks with milk, mayonnaise, and seasonings to make a cream.
Combine the yolk cream and chopped whites to make the egg mayo filling.
Spread mustard on the bread and generously fill with the egg mayo mixture.

Cooking tips

Add the milk gradually, not all at once, to control the consistency and prevent the filling from becoming too runny.
Spreading mustard on the cut side of the bread cuts the richness of the eggs and adds a refreshing note.
Using soft, moist milk bread best replicates the texture of Japanese convenience store egg sandwiches.
