Japanese Egg Sandwich (Tamago Sando)

1. Gather all the ingredients.

To Make the Egg Salad

1. Put 3 large eggs (50 g each w/o shell) in a medium saucepan and add enough water to cover by 1 inch (2.5 cm). Bring it to a boil on medium heat. Once boiling, cook for 12 minutes.
2. Once it’s finished cooking, transfer the eggs to iced water to stop the cooking. Let them cool completely and peel the eggshells.
3. Transfer the peeled eggs to a bowl and mash with a fork. Try to mash the egg whites into small, same-sized pieces.
4. Add ¼ tsp sugar and ¼ tsp Diamond Crystal kosher salt to the eggs.
5. Add ⅛ tsp freshly ground black pepper and 2 tsp milk.
6. Add 2 Tbsp Japanese Kewpie mayonnaise and mix very well. Taste and sprinkle more salt and pepper, if needed.

To Assemble the Tamago Sando

1. Set out 4 slices shokupan (Japanese milk bread). Spread salted butter on top of each slice. For each sandwich, spread the egg salad on one of the slices.
2. Put the other slice of bread, buttered side down, on top of the egg salad. Place the sandwiches between two plates to compress slightly. Set aside for 5 minutes.
3. Cut the crusts off the bread. Tip: Don‘t throw away the crusts. Repurpose them to make Shokupan Crust Rusks. These crunchy, buttery snacks are so delicious! You can make them now or freeze those crust strips and make them later.
4. Cut the sandwiches in half. They‘re now ready to serve.
