Best bread for this egg salad sandwich
To make the perfect soft, fluffy texture, in Japan, we use milk bread. This is one of the secrets to making this egg sandwich extra fluffy and delicious. You can find it at your local Japanese store.
You need soft bread for this recipe. So, if you aren't able to find Japanese milk bread, use brioche as a replacement and make sure to cut the crust off.
Japanese egg salad sandwich ingredients
Japanese Kewpie mayonnaise is a globally known brand. It’s now pretty readily available at local supermarkets in many places around the world.
With an umami rich egg yolk flavour and a silky smooth texture, Kewpie Mayo is indispensable. It’s essential for how to make this Japanese mayo sandwich.
If it's not available, I’ve added the link below to my homemade Japanese mayo which is based on key Kewpie Mayo ingredients, and is really straightforward to make.
Of course, this recipe is all about the eggs! So use fresh, ideally organic, eggs if you can. Japanese eggs have to adhere to strict regulations and are super fresh and almost always organic. The freshness and quality of the eggs is one of the reasons Japanese egg sandwiches are so delicious, so it’s worth getting good quality eggs.
Mustard and butter
Spread the mustard and butter mix before you place the cooked egg on the bread. Japanese mustard (karashi) is traditionally used. You can replace it with Dijon mustard if it's not available.
Place butter and mustard mix on both bread slices. Don't skip this. You will be aware the differences in your first bite. Then cut the edge crust off (see my tip below for using the crust).
How to Make Japanese Egg Sandwich
You've got soft fluffy bread slices, ideally Japanese milk bread, fresh eggs and Kewpie Mayo. Now you’re ready! Let's get started!
Egg whites and yolks play different roles for this egg salad sandwich. While egg whites create texture, the yolks add intense egg flavour. So, once boiled, you need to separate them.
Make a cut on the surface of the hard boiled eggs. This helps you separate them easily. Egg yolks are seasoned with milk, salt, sugar and mayo.
Cut egg whites not into thin dices. This is perfect to keep the egg filling fluffy inside and avoid deflating itself with its own weight.
Egg yolk sauce
Smooth over the egg yolks with a spatula and season them with salt, sugar and mayo. This is the secrete to create an intense egg flavour for this sandwich! Make the egg yolk mix fluffy with the spatula.
Add sliced egg whites in the egg yolk mix.
Place butter and mustard mix on both bread slices. Don't skip this. You will be aware the differences in your first bite. Then cut the edge crust off.
Place the bread on cling film (Saran wrap). From here, things need to be quick but should be done surely.
Top the seasoned egg mix filling on the bread slice. No need to spread it out but simply top it on. It will naturally spread over the bread. Avoid pushing the filling. We need to feel the luxury of every bite with this creamy, fluffy filling.
Place the another bread slice on top. Then wrap up the sandwich with a cling film. This wrapping helps to avoid leaking the sauce out of the bread.
And It's optional but put the sandwich in the fridge for 15 minutes and so that it's easy to cut it into two.
That's it! Serve immediately. Enjoy!
How to save Japanese egg sandwich
This sandwich is best enjoyed within a day. It can last three days in the fridge with cling film, Saran wrap or in an air-tight container.
Why is Japanese egg sandwich crustless?
A main reason is to create a harmony and balance in texture. Japanese egg salad sandwich is fluffy, creamy and silky smooth. The chewy edge crust can be an obstacle for this. Also this is the reason why fluffy bread like Japanese milk bread (shokupan) is used.
The leftover crust? I use them for French toast sticks or bread crumbs (panko).
