Step‑by‑Step Instructions for Japanese Egg Sandwich (Tamago Sando)
Step 1: Boil the Eggs
Begin by placing 4 large eggs in a pot and covering them with cold water. Bring the water to a rolling boil over medium-high heat and let the eggs boil for exactly 10 minutes. Once the time is up, carefully transfer the eggs to an ice bath to cool for about 5 minutes. This cooling process makes peeling them much easier while ensuring they stay tender.
Step 2: Mash the Boiled Eggs
Once the eggs have cooled, gently tap them on the counter to crack the shells and peel them under running water to facilitate the process. Next, place the peeled eggs in a mixing bowl and mash them with a fork until they reach a chunky yet creamy consistency. This will provide the perfect base for your Japanese Egg Sandwich filling.
Step 3: Mix the Filling
Add 2 tablespoons of Japanese mayonnaise, 1 teaspoon of sugar, and 1 teaspoon of salt to the mashed eggs in the bowl. Use a spatula or a fork to blend these ingredients together until the mixture is well combined and creamy. Taste the filling and adjust the seasoning if desired, enhancing the delicious flavor profile of your Tamago Sando.
Step 4: Prepare the Bread
While the egg mixture settles, take 4 slices of soft white bread and lay them on a clean surface or cutting board. This type of bread is essential for achieving the fluffy texture associated with authentic Japanese Egg Sandwiches. Ensure the slices are fresh and free of crust if you prefer a softer bite.
Step 5: Assemble the Sandwiches
Spread the egg filling evenly across two slices of bread, ensuring a generous layer for that delectable bite. Place the remaining two slices of bread on top to create two complete sandwiches. Gently press them together to secure the filling while maintaining the puffiness of the bread, ready for slicing.
Step 6: Cut and Serve
Using a sharp knife, cut each sandwich into halves or quarters, depending on your preference for serving sizes. Arrange the pieces neatly on a plate, showcasing the creamy filling. Your Japanese Egg Sandwich (Tamago Sando) is now ready to be served, offering a delightful taste of Japan that’s perfect for any occasion.
