Ingredients

  • 1.5 lb potatoes, waxy
  • 1 medium carrot
  • 1 medium cucumber
  • ½ cup mayonnaise
  • 1 tablespoon soy sauce
  • 1 tablespoon mirin (sweet rice wine)
  • ½ tablespoon rice vinegar

Instructions

  1. 1

    Cut potatoes into 1-inch cubes by first cutting each potato lengthwise in half, then crosswise into 1-inch-thick half-moons, then lengthwise again to make small cubes—roughly the size of dice.

  2. 2

    Cut carrot into 1/4-inch-thick coins by slicing straight down through the carrot crosswise, rotating it slightly after each slice so all pieces are similar size.

  3. 3

    Cut cucumber in half lengthwise from tip to root, then place flat-side down and slice lengthwise into 1/4-inch-thick spears; rotate and cut crosswise into 1/4-inch chunks.

  4. 4

    Fill a medium pot three-quarters full with water and bring to a boil over high heat, watching until large bubbles break the surface rapidly and steam rises strongly.

  5. 5

    Add potato cubes to the boiling water and stir with a wooden spoon to prevent sticking; cook until a fork pierces a potato cube with no resistance, about 10 minutes.

  6. 6

    Add carrot coins to the pot and cook for 2 more minutes, stirring occasionally, until the carrot is just softened but still has slight resistance when pierced.

  7. 7

    Place a colander in the sink and slowly pour the entire pot contents through it, allowing water to drain completely; do not rinse the vegetables.

  8. 8

    Spread the drained potatoes and carrots on a plate in a single layer and let them cool for 5 minutes until they no longer steam—this allows the dressing to coat evenly.

  9. 9

    In a small bowl, pour 1 tablespoon soy sauce, 1 tablespoon mirin, and 0.5 tablespoon rice vinegar; stir with a spoon until well mixed and the sugar from the mirin dissolves, about 30 seconds.

  10. 10

    In a large mixing bowl, combine the mayonnaise and the soy-mirin mixture; whisk together with a fork until evenly blended and creamy, about 1 minute.

  11. 11

    Add the cooled potato-carrot mixture and cucumber chunks to the dressing and gently stir with a rubber spatula until all vegetables are evenly coated, about 1 minute.

  12. 12

    Taste a spoonful and sprinkle in a small pinch of salt if desired; stir once more and transfer to a serving bowl.
