Japanese Potato Salad
This potato salad reminds me of many nights spent at izakayas in Japan.
This recipe is actually two in one! You first make a homemade Japanese-style mayonnaise and then prep & assemble the potato salad. It is a bit involved but worth every minute of effort.
Ingredients
- 1 whole egg
- 1 egg yolk
- 1 tablespoon Dijon mustard

Directions
To make the mayonnaise, place the egg and yolk, Dijon mustard, karashi mustard powder, rice vinegar, liquid shio koji and salt in a food processor or blender. Blend for about 30 seconds. Slowly add the oil, being careful not to break the mixture. If it gets too thick, add water 1 tablespoon at a time to loosen.
Mix the cucumber slices and 1 teaspoon salt in a bowl. Top them with the konbu, then place another bowl on top with a weight inside to press down. Every 10 minutes, remove the weight and gently massage the cucumbers, draining the liquid in the bowl. Repeat approximately 4 to 5 times until the they start to darken in color slightly and become pliable.
Bring the carrots, water, butter, sugar, ½ teaspoon salt and liquid shio koji to a boil in a large skillet, and reduce until the liquid is almost gone and the carrots are cooked through, about 10 minutes. Set aside.
In a separate saucepan, boil the whole potatoes in salted water until tender. Drain, cool slightly, then crush in hands lightly. Meanwhile, add the ginger, rice vinegar, sugar, ½ teaspoon salt and dashi to another small saucepan, bring to a boil, and immediately turn off.
Add the ginger mixture to the hot potatoes, then add the cucumbers, carrots and mayonnaise. Season to taste with salt.
