Step-by-step Preparation of Japanese Egg Sandwich
Creating a delicious Japanese egg sandwich at home is easier than you might think! With a few simple steps, you can whip up a satisfying meal that’s perfect for breakfast, lunch, or even a snack. Let’s dive into the preparation process, shall we?
Gather the Ingredients
Before we get cooking, it's essential to gather all the necessary ingredients. For this Japanese egg sandwich, you'll need:
- 3 large eggs (50 g each without shell)
- ¼ teaspoon sugar
- ¼ teaspoon Diamond Crystal kosher salt
- ⅛ teaspoon freshly ground black pepper
- 2 teaspoon milk
- 2 tablespoon Japanese Kewpie mayonnaise
Having everything laid out will make the process smoother and more enjoyable. Sometimes, I like to prep my ingredients in advance and even have a cup of tea while I’m at it. It sets a nice cooking vibe!
Boil the Eggs
Start by placing the 3 large eggs in a medium saucepan. Add enough cold water to cover them by about 1 inch (2.5 cm). Bring the water to a boil over medium heat. Once the water is bubbling away, let your eggs cook for 12 minutes. This timing is crucial; it ensures that your eggs are perfectly hard-boiled without that unpleasant greenish ring.
Cool and Peel the Eggs
After the eggs are done cooking, it's time to cool them down. Transfer the eggs to a bowl filled with ice water to stop the cooking process. Allow them to cool completely—this usually takes about 5-10 minutes. After cooling, gently tap the eggs on a hard surface to crack the shell and peel them under running water. This trick helps with the peeling and makes it much easier!
Make the Egg Salad Mix
Now that you have your peeled eggs, it’s time to make the star of the show: the egg salad mix! Transfer the egg whites and yolks into a bowl and mash them with a fork. Remember, you can aim for small, uniform pieces to get that perfect texture. Add ¼ teaspoon sugar, ¼ teaspoon salt, ⅛ teaspoon freshly ground black pepper, 2 teaspoon milk, and 2 tablespoon Kewpie mayonnaise. Mix everything well until all the ingredients are combined and creamy. It’s one of those moments you wish you could dive into the bowl!
Assemble the Sandwich
Now comes the fun part: assembling your Japanese egg sandwich. Start with two slices of soft white bread (or your preferred choice). Spread the luscious egg salad mix generously between the slices. If you’re feeling adventurous, add some Turkey bacon or Chicken ham for a variation. Cut your sandwich in half, and voilà! You have a delightful and simple Japanese egg sandwich ready to be devoured.
Enjoy it fresh, or pack it for lunch—either way, it’s bound to be a hit. Happy cooking!
