Whether served for breakfast, brunch, café menus, or gourmet lunch boxes, the Japanese Egg Sando is easy to prepare yet elegant enough to impress every customer.

Ingredients

For the Filling

• ◆Eggs
• ◆Kewpie Japanese Mayonnaise
• ◆Milk
• ◆Salt
• ◆Black Pepper

For the Sandwich

• ◆Japanese Milk Bread (Shokupan)
• ◆Butter

Step 1: Prepare the Eggs

Boil the eggs until fully cooked. Immediately transfer them into cold water and allow them to cool completely. Once cooled, peel the eggs carefully. Separate the yolks from the egg whites.

Step 2: Make the Creamy Egg Filling

Place the egg yolks into a mixing bowl and mash or whip them until smooth and creamy. Add Kewpie Japanese Mayonnaise, a pinch of salt, freshly ground black pepper, and a small splash of milk. Mix thoroughly until the filling becomes thick, smooth, and velvety.

The Kewpie mayonnaise gives the filling its signature rich flavour, while the milk creates the light, fluffy texture that makes Japanese Egg Sando so unique.

Step 3: Fold in the Egg Whites

Finely chop the egg whites into small, even pieces. Gently fold them into the creamy yolk mixture until everything is evenly combined. The chopped egg whites add texture while maintaining the sandwich's soft and delicate bite.

Step 4: Prepare the Bread

Take slices of soft Japanese Milk Bread (Shokupan) and carefully trim off the crusts. Spread a generous layer of butter evenly over the inside of each slice. The butter enhances the richness while helping keep the bread soft and moist.

Step 5: Assemble the Sandwich

Spread a generous amount of the creamy egg mixture evenly over one slice of buttered bread. Place the second slice on top and gently press the sandwich together without flattening the soft bread.

Step 6: Wrap, Slice & Serve

Wrap the sandwich neatly in butter paper and allow it to rest for a few minutes. This helps the filling hold its shape and makes slicing easier. Using a sharp knife, cut the sandwich neatly into two equal halves.

Serve immediately and enjoy the beautiful cross-section of the rich, creamy filling inside the soft, fluffy bread.
