Method
 

Step 1: Cook the Eggs
  1. Place the eggs in a saucepan and cover with cold water. Bring to a boil over medium heat. Once boiling, reduce heat slightly and cook for 10 minutes.
Step 2: Cool and Peel
  1. Transfer the eggs to cold water and let them cool completely. Peel the eggs and pat dry.
Step 3: Mash the Eggs
  1. Place the peeled eggs in a mixing bowl. Use a fork or masher to mash them until very fine and creamy. The texture should be smooth, not chunky.
Step 4: Season the Filling
  1. Add Japanese mayonnaise, milk, salt, sugar, and black pepper to the eggs. Mix gently until fully combined and silky smooth.
Step 5: Prepare the Bread
  1. Lightly butter one side of each slice of milk bread. This helps prevent sogginess and adds richness.
Step 6: Assemble the Sandwich
  1. Spread a generous layer of the egg mixture onto the unbuttered side of two bread slices. Sprinkle chopped chives on top if using. Place the remaining bread slices on top, buttered side facing inward.
Step 7: Trim and Slice
  1. Trim the crusts if desired for a traditional look. Slice each sandwich in half.
Step 8: Serve
  1. Serve immediately, or chill briefly for a more classic convenience-store style texture.
