This mayo is richer and slightly sweeter than regular mayo, giving the egg salad its signature flavor.
Sugar:
A touch of sugar balances the savory notes and enhances the overall taste.
Salt & Black Pepper:
Essential seasonings that bring out the natural flavors of the eggs.
Milk or Plant Milk (Optional):
Adds extra creaminess, especially if using hard-boiled eggs.
Japanese Milk Bread:

Unsalted Butter:
Buttering the bread adds richness and helps prevent sogginess.

How to Prepare Japanese Egg Salad Sandwich

Step 1:
Prepare an ice bath in a large bowl. Bring a pot of water to boil, then carefully lower the eggs and boil for 7 minutes for soft-boiled or 10 minutes for hard-boiled.
Step 2:
Transfer the eggs to the ice bath for 2 minutes to stop cooking, then peel while still lukewarm.
Step 3:
Mash the eggs in a bowl with sugar, salt, and pepper until the pieces are smaller than a pea.
Step 4:
Add mayonnaise (and milk if using) and mix well. Adjust seasoning if needed.
Step 5:
Butter the bread slices, spread the egg salad on one slice, and top with another slice. Press gently, trim the crusts, and slice in half.

They blend better with the mayo when slightly warm, creating a smoother texture.
Toast the Bread Lightly:
For extra texture, lightly toast the bread before assembling the sandwich.

Make-Ahead and Storage
Store Egg Salad Separately:
Keep the egg salad in an airtight container in the fridge for up to 2 days.
Assemble Just Before Eating:
To prevent soggy bread, assemble the sandwich right before serving.
No Freezing:
Egg salad doesn’t freeze well due to the mayo texture changing.
