Step-by-Step Preparation for Japanese Egg Sandwiches
Making the perfect Japanese Egg Sandwich not only requires good ingredients but also a bit of patience and technique. Let's dive into the straightforward steps that will guide you through creating a delicious and satisfying sandwich.
Boil the eggs
The first step in our Japanese Egg Sandwich recipe begins with boiling the eggs. You’ll want to hard-boil six large eggs while also making one medium-boiled egg for added creaminess.
- Fill a pot with water and bring it to a boil over medium-high heat.
- Gently add all six eggs and let them boil for exactly 7 minutes and 30 seconds.
- Meanwhile, prepare an ice bath by filling a bowl with cold water and ice.
- At the 7-minute and 30-second mark, carefully remove one egg and transfer it to the ice bath. This will halt the cooking process for the medium-boiled egg.
- Let it cool for 2 minutes, then peel it slowly and set it aside.
- For the remaining eggs, continue boiling them for an additional 1 minute and 30 seconds (totaling 9 minutes) before placing them in the ice bath for another 2 minutes.
Prepare the filling
Now, let’s create that rich and creamy filling that makes this sandwich delightful.
- Take your hard-boiled eggs, slice them in half, and scoop the yolks into a mixing bowl. Use a fork to mash the yolks into fine pieces.
- To the egg yolks, add:
-
2 teaspoons of whole milk
-
4 tablespoons of Kewpie mayonnaise (a must for authenticity)
-
½ teaspoon of white granulated sugar
-
¾ teaspoon of salt
-
¼ teaspoon of black pepper
Mix well until everything is combined. For a refreshing touch, feel free to add 1 tablespoon of finely chopped chives. Let this mixture chill in the fridge for about 10 minutes while you prepare the bread.
Assemble the sandwich
With your filling ready and chilled, it’s time to put together your sandwich.
- Take four slices of shokupan (Japanese milk bread) and cut off the crusts for that classic presentation.
- Spread a thin layer of unsalted butter on one side of each slice of bread.
- Slice your medium-boiled egg in half and place it face down on two slices of bread.
- Spoon the chilled filling around and on top of the medium-boiled egg, ensuring it’s well-covered.
- Top it with another slice of buttered bread, then repeat with the remaining ingredients to create a second sandwich.
Final touches
The last step is all about getting those sandwiches ready to serve.
- Carefully slice each sandwich in half, exposing the creamy filling and that beautiful medium-boiled egg.
- Serve immediately while they’re fresh and the bread is still soft.
These Japanese Egg Sandwiches make for a delightful snack or a light lunch and are sure to impress with their smooth filling and comforting taste. Enjoy this flavor-packed experience with your favorite drink or salad!
