  • 1 Tbsp Japanese mayonnaise
  • kosher/sea salt (use half for table salt)
  • Freshly ground black pepper
  • pinch sugar (optional, see Notes)


  1. Gather all the ingredients. (Make a hard boiled egg on the previous day to save time in the morning.)

  3. Add 1 Tbsp. of mayonnaise and mix well. If it's not moist, you can add 1/2 Tbsp. more.

  4. Season with salt and pepper (and sugar if you like). I like to add salt and pepper a bit more than what I usually add to give good flavor.

  5. Spread the egg mixture on top a piece of bread and put another slice of bread on top.
