- Salt – Just 1/4 teaspoon enhances the taste; adjust based on your preference.
- Black Pepper – 1/4 teaspoon adds a subtle warmth and depth to the salad.
- Milk – 1 to 2 teaspoons (optional) keeps the hard-boiled egg salad moist and creamy.

For the Sandwich
- Japanese Milk Bread – 4 slices of soft, sweet bread that create the perfect backdrop for your egg salad.

Step‑by‑Step Instructions for Japanese Egg Sandwich
Step 1: Prepare Ice Bath
Begin by filling a large bowl with ice and cold water, creating an ice bath that will help stop the cooking process. This step is vital for your Japanese Egg Sandwich, as it ensures your eggs maintain a delicate texture. Set the ice bath aside while you prepare to cook your eggs.
Step 2: Boil Eggs
Carefully place your large organic eggs in a pot of boiling water, ensuring they are fully submerged. For soft-boiled eggs, let them cook for about 7 minutes, and for hard-boiled eggs, aim for 10 minutes. Keep an eye on the clock, as precise timing is key for achieving the perfect creamy yolk in your egg salad.
Step 3: Chill Eggs
Once the eggs have finished cooking, use a slotted spoon to transfer them immediately into the ice bath. Allow the eggs to chill for about 2 minutes; this will make peeling easier and help retain their creaminess for your Japanese Egg Sandwich. After chilling, peel the eggs gently while they are still warm.
Step 4: Make Egg Salad
In a mixing bowl, mash the peeled eggs with a fork until they reach a creamy consistency. Add in the sugar, salt, black pepper, and Japanese mayonnaise, mixing until everything is well combined. If you desire a moister consistency, stir in 1 to 2 teaspoons of milk. Taste, and adjust the seasoning if necessary to perfect your egg salad.
Step 5: Assemble Sandwiches
Take your four slices of Japanese milk bread and spread softened unsalted butter evenly on one side of each slice. On two of the slices, generously layer your egg salad, then top with the remaining slices, buttered side down. For the finishing touch, trim the crusts off for a classic look and slice the sandwiches in half to serve.
Step 6: Serve & Store
Serve your delightful Japanese Egg Sandwich immediately for the best flavor and freshness. If you’re preparing ahead, wrap the sandwiches in plastic wrap and store them in the refrigerator for up to 2 days. This simple storage solution helps maintain their moisture, so you can enjoy them later as a tasty snack or light meal.

How can I tell if my eggs are fresh or spoiled?
A great method to check the freshness of your eggs is the water test! Fill a bowl with water and gently place the egg inside. If it sinks and lies flat, it’s fresh. If it stands upright or floats, it’s time to toss it. Always choose the freshest eggs for your Japanese Egg Sandwich!
