RECIPE: Japanese Potato Salad with Sobacha (Buckwheat Tea)

RECIPE: Sobacha (Buckwheat Tea) Potato Salad

You may be surprised to find out that potato salad is a popular home-cooked dish in Japan. Different than in the west, the Japanese version includes creamy, smooth potatoes mixed with crunchy vegetables. Here we add leftover soba (buckwheat) from your cup of sobacha (buckwheat tea) for an additional layer of texture and nutty taste.

Servings: 4
Prep time: 10mins
Cooking time: 4mins


  • 2 potatoes (250g)
  • ½ cup celery (thinly sliced)
  • ½ cup cucumber (thinly sliced)
  • ½ cup red or yellow pepper (chopped)
  • Pinch of salt
  • ½ cup of leftover buckwheat from the Sobacha (Buckwheat) Tea after you've enjoyed a cup of tea (available in our Japanese Green and Specialty Teas: “Ryu” Care Package)

  1. Rinse the potatoes and remove the eyes. Place in a pot and top with water until the potatoes are submerged. Cook on high heat for 25 mins or until the potatoes are fully cooked (when you can easily poke a fork in them).
  2. Drain the potatoes and while still hot, mash them with the anchovies, soy sauce, rice vinegar and garlic.

  6. Add the leftover soba and Japanese mayo. Mix together and serve. Sprinkle with black pepper to taste and garnish with optional toppings if desired.


  • For a creamier texture, remove the skin of the potatoes after you boil them.
    • Make sure to add the rice vinegar while the potatoes are still hot so they absorb the vinegar nicely.
    • You can add more soba for additional texture and taste.
    • You can swap mayonnaise for greek yogurt or sour cream. Be sure to add a little salt to adjust the taste.

    Storage time:Can be stored in the fridge in an air-tight container for up to 3 days. Please re-toss before serving.
