Ingredients For Japanese Egg Salad Sandwich
Tofu: Firm tofu is used as a base to replicate the texture of eggs.
Vegan mayonnaise: Adds creaminess and binds the ingredients together.
Yellow mustard: Provides a tangy flavor that complements the tofu.
Black salt: Gives the mixture an egg-like flavor due to its sulfur content.
Turmeric: Adds a yellow color to mimic the appearance of egg yolk.
Green onions: Adds a fresh, mild onion flavor and a bit of crunch.

Technique Tip for This Recipe
When crumbling the tofu, aim for a texture that mimics the consistency of hard-boiled eggs. This can be achieved by using a fork to break it down into small, irregular pieces. The black salt (kala namak) is crucial for imparting an egg-like flavor, so make sure to mix it thoroughly with the vegan mayonnaise and mustard. For an extra touch of authenticity, lightly toast the Japanese milk bread before assembling the sandwich.

How to Store / Freeze This Recipe
- To keep your Japanese Egg Salad Sandwiches fresh, store them in an airtight container. This will prevent the bread from drying out and the tofu mixture from losing its flavor.
- Place a piece of parchment paper between each sandwich to avoid them sticking together. This is especially useful if you plan to stack them.
- Store the container in the refrigerator. The sandwiches will stay fresh for up to 2 days. Beyond this, the bread may become soggy, and the tofu mixture might lose its texture.
- If you need to prepare the sandwiches in advance, consider storing the tofu mixture separately in an airtight container. When ready to serve, simply spread the mixture onto the bread.
- For freezing, wrap each sandwich individually in plastic wrap or aluminum foil. This will help maintain their shape and prevent freezer burn.
- Place the wrapped sandwiches in a freezer-safe bag or container. Label with the date to keep track of freshness.
- When ready to enjoy, thaw the sandwiches in the refrigerator overnight. For a quicker option, you can microwave them on a low setting for a few seconds, but be cautious as this may alter the texture of the bread.
- If you prefer a fresher taste, freeze only the tofu mixture and prepare the sandwiches fresh when needed. The tofu mixture can be stored in the freezer for up to 1 month.
