  • 1 teaspoon chopped chives

  • Pinch of paprika

Preparing the Eggs

Step 1: Boil the Eggs

Place the eggs in a saucepan.

Cover with cold water.

Bring to a boil over medium heat.

Cook for 10–11 minutes until firm.

Step 2: Cool

Transfer the eggs immediately into ice water.

Allow them to cool for about 5 minutes.

Peel carefully.

Making the Filling

Separate the yolks from the whites.

Mash the yolks until smooth.

Finely chop the egg whites.

Combine both in a bowl.

Add:

  • Japanese mayonnaise
  • Butter
  • Dijon mustard (optional)
  • Salt
  • Black pepper

Mix until creamy while leaving small pieces of egg white for texture.

If using herbs, gently fold them in at the end.

Preparing the Bread

Use fresh Shokupan.

Spread a thin layer of softened butter on one side of each slice.

Butter helps keep the bread soft and prevents the filling from making it soggy.

Assembling the Sandwich

Spread the egg mixture generously over two slices of bread.

If desired, add lettuce or cucumber for extra freshness.

Place the remaining slices on top, buttered side facing inward.

Press gently without flattening the bread.

Chilling (Optional)

Wrap the sandwiches in plastic wrap.

Refrigerate for 10–15 minutes.

This helps the filling firm up slightly, making the sandwiches easier to slice neatly.

Cutting and Serving

Trim the crusts for the traditional Japanese look.

Cut into:

  • Triangles
  • Rectangles
  • Finger sandwiches

Serve immediately while the bread is still soft and fresh.
