FAQs

What makes Japanese egg sandwiches different?

Japanese egg sandwiches use soft, fluffy shokupan bread and a rich, creamy egg filling with Kewpie mayo for a smoother texture.

Can I use regular mayonnaise instead of Kewpie?

Yes, but Kewpie mayo has a richer, slightly tangy flavor. You can mimic it by adding a dash of rice vinegar and a little sugar to regular mayo.

How do I make my egg filling smoother?

Mash the eggs thoroughly or push them through a fine-mesh sieve for an extra silky texture.

Can I use pre-cooked eggs?

Freshly boiled eggs work best, but you can use pre-cooked eggs if they’re not too dry.

Do I have to remove the crusts?

No, trimming the crusts is traditional but optional. Keeping them adds extra texture.

Can I add other ingredients to the filling?

Yes! Try adding chopped chives, avocado, or a sprinkle of paprika for extra flavor.

What’s the best bread for this sandwich?

Japanese milk bread (shokupan) is the best choice for its soft, pillowy texture, but any soft white bread works.

Can I make this sandwich ahead of time?

Yes, but it’s best eaten fresh. If making ahead, store in the fridge wrapped in plastic wrap to keep the bread soft.

Is Tamago Sando served warm or cold?

It’s typically served at room temperature or slightly chilled for the best texture.

Can I make this recipe without butter?

Yes, but the butter adds a subtle richness that enhances the overall flavor.

Tamago Sando is a simple yet irresistible Japanese egg sandwich that delivers a creamy, fluffy texture with every bite. Whether you’re looking for a quick breakfast, an easy snack, or a light lunch, this sandwich is sure to satisfy. Try out different variations and enjoy a taste of Japan at home!
