Tamago Sando (Japanese Egg Sandwich)

A Japanese egg-salad sandwich — boiled eggs folded into mayo and piled into soft milk bread. Famous as a convenience-store staple. Once the eggs are boiled it's just mix and assemble, so anyone can make this creamy, comforting sandwich in 15 minutes.

Tips & Variations

Variations

  • With a soft egg: Tuck a whole soft-boiled egg in the center for a runny yolk.
  • Kewpie style: A little Kewpie mayo and sugar for that konbini flavor.
  • Mentaiko/ham: Add spicy cod-roe mayo or ham for more savoriness.
  • Press it: Gently pressing and resting gives clean, photogenic cross-sections.

Tips

  • Use soft milk bread with the crusts off — it's key to the fluffy texture.
  • Butter the bread thinly so the filling's moisture doesn't make it soggy.
  • Mash yolks fine but keep some white chunky for contrast.
  • Kewpie mayo (with a pinch of sugar) gives the signature rich, slightly sweet taste.
  • Wrap and rest before cutting so it holds together in neat slices.
