Japanese Egg Sandwich Ingredients
Let’s get ready to create the beloved Tamago Sando with these simple ingredients!
For the Egg Filling
- Eggs – Use fresh, high-quality eggs for that fluffy, custard-like filling, and make sure they’re at room temperature for even cooking.
- Kewpie Mayonnaise – This richer alternative to regular mayonnaise brings a creamy texture and unique tang; if you can’t find it, regular mayonnaise will work in a pinch.
- Mustard (optional) – A small dash adds a delightful zing to the filling, enhancing the flavor profile.
- Salt & Pepper – Essential for elevating the natural flavors of the eggs while balancing the creaminess.
For the Bread
- Soft White Bread – Ideally, use Japanese milk bread (shokupan) for its softness and subtle sweetness; trimming the crusts makes for a prettier sandwich.
- Unsalted Butter – Adding richness to the bread, it also helps keep the sandwich moist while enhancing flavor.
With these simple but wonderful ingredients, you’re just a few steps away from enjoying your delicious Japanese Egg Sandwich Tamago Sando!
Step‑by‑Step Instructions for Japanese Egg Sandwich Tamago Sando
Step 1: Boil the Eggs
Begin by placing fresh, room-temperature eggs in a saucepan and covering them with cold water. Bring the water to a rapid boil over medium heat, then cover the pot and turn off the heat. Let the eggs steep in the hot water for 9-12 minutes, ensuring they cook through while becoming perfectly tender.
Step 2: Cool the Eggs
Once the eggs have finished cooking, carefully transfer them to a bowl filled with ice-cold water. Allow the eggs to sit in the ice bath for about 5 minutes. This crucial step will stop the cooking process and make peeling them much easier, leaving the eggs intact for your filling.
Step 3: Prepare the Bread
While the eggs are cooling, take your soft white bread and trim off the crusts using a sharp knife. Aim for neat, square pieces about the same size as the filling slices. This will create a soft, inviting base for your Japanese Egg Sandwich Tamago Sando that’s visually appealing and easy to handle.
Step 4: Mash the Eggs
Once the eggs are completely cooled, gently tap them to crack the shells and peel them. Place the peeled eggs into a mixing bowl and mash them with a fork until slightly coarse. You want a texture that is fluffy yet still provides some structure, allowing for a delightful egg filling in your sandwich.
Step 5: Mix the Filling
To the mashed eggs, add a generous dollop of Kewpie mayonnaise, a pinch of salt, and pepper to taste. If using mustard, add it as well for an extra zing. Stir everything together using a spatula until the mixture is creamy and well-combined, but be careful not to overmix—some texture adds character to your Tamago Sando.
Step 6: Butter the Bread
Take your trimmed bread slices and spread a thin layer of softened unsalted butter on one side of each slice. This not only adds richness but also helps the sandwich stay moist and flavorful. Ensure you cover the surface evenly, providing a subtle creaminess in each bite of the Japanese Egg Sandwich Tamago Sando.
Step 7: Assemble the Sandwich
On two of the buttered slices, generously spoon the egg filling, spreading it out evenly. Then, take the remaining slices, buttered side down, and place them on top of the filled slices. Press down gently to secure the sandwich, making sure the egg mixture is snugly tucked between the soft pieces of bread.
Step 8: Cut the Sandwich
Using a sharp knife, slice the assembled sandwiches into triangles or rectangles, depending on your preference. A clean cut will showcase the creamy filling beautifully. Serve your assembled Japanese Egg Sandwich Tamago Sando immediately, or wrap them carefully for later enjoyment.
