Japanese mayonnaise: Adds a rich, creamy, and slightly tangy flavor to the egg mixture.
Sugar: Adds a touch of sweetness to balance the flavors.
Salt: Enhances the overall taste of the egg salad.
White bread: Soft and crustless, perfect for holding the creamy egg mixture.

How to Store / Freeze This Recipe
Allow the egg salad mixture to cool completely before storing. This prevents condensation and keeps the bread from becoming soggy.
Store the sandwiches in an airtight container. This helps maintain their freshness and prevents them from absorbing any unwanted odors from the refrigerator.
If you plan to enjoy the sandwiches within a day or two, keep them in the refrigerator. They will stay fresh for up to 2 days.
For longer storage, consider freezing the egg salad mixture separately. Place it in a freezer-safe container or a resealable plastic bag, ensuring to remove as much air as possible. This will keep the mixture fresh for up to a month.
When ready to use the frozen egg salad mixture, thaw it in the refrigerator overnight. Avoid thawing at room temperature to prevent any risk of bacterial growth.
Once thawed, give the egg salad mixture a good stir to restore its creamy texture. You may need to add a bit more japanese mayonnaise to achieve the desired consistency.
Assemble the sandwiches with fresh bread just before serving. This ensures the bread remains soft and doesn't become soggy from the egg salad mixture.
If you prefer to freeze the entire sandwiches, wrap each one tightly in plastic wrap, followed by a layer of aluminum foil. This double-layer protection helps prevent freezer burn.
Label the wrapped sandwiches with the date to keep track of their storage time. Frozen sandwiches are best consumed within 1 month for optimal taste and texture.
To enjoy the frozen sandwiches, thaw them in the refrigerator for a few hours or overnight. For a quicker option, you can also use the defrost setting on your microwave, but be cautious to avoid overheating.
How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Wrap the sandwiches in aluminum foil to prevent them from drying out. Place them on a baking sheet and heat for about 10 minutes or until warmed through.
Use a toaster oven set to a low temperature. Place the sandwiches on the rack and heat for 5-7 minutes. This method helps maintain the crispiness of the bread.
For a quick reheat, use a microwave. Wrap the sandwiches in a damp paper towel to keep them moist. Microwave on medium power for 30-45 seconds. Check and add more time if needed.
If you have a panini press, preheat it and place the sandwiches inside. Press for 3-4 minutes until the egg mixture is warm and the bread is slightly crispy.
For a stovetop method, heat a non-stick skillet over medium heat. Place the sandwiches in the skillet and cover with a lid. Heat for 2-3 minutes on each side, pressing down slightly to ensure even warming.
