Walnut Yubeshi

Ingredient 1 Batch 1 Batch
walnut pieces 1½ tsp. 50g
shiratamako ⅓ oz. 120g

Kurumi yubeshi — walnut yubeshi — is a lightly sweet Japanese confection with contrasting textures of firm walnuts in a soft, chewy dough.


  1. Roast walnuts at 180°C (350°F) for 7 minutes, or toast lightly in a frying pan. Chop coarsely once done.
  2. If you’re using kurozato in chunk form, chop it into small pieces.
  3. Generously dust a cookie sheet with potato starch or corn starch.


  1. Mix ingredients.
    Initially mixed ingredients Whisk together the shiratamako and water in a bowl until well blended. Add sugar and whisk until completely blended. Strain mixture through a fine-mesh strainer into a microwave-safe bowl. Stir in walnuts with a rubber spatula.
  2. Cook in microwave.
    Cover mixture and microwave on high for 1 minute 30 seconds. Stir well with the spatula. Cover and microwave for another 1 minute 30 seconds. Stir again, until it starts to look a little transparent.

  3. Roll out and cut.
    Rolled-out yubeshi dough Immediately turn out hot dough onto the prepared cookie sheet and roll out into a roughly 1cm (half-inch) thick sheet. Leave to cool. Once cool, cut into pieces of whatever shape and size you prefer.


  • It’s important to blend the shiratamako very well, and to strain after blending in the sugar.
  • Shiratamako is a type of specialty rice flour; you may have to go to a Japanese specialty store to find it.
  • Kurozato — also called kokutou — is an unrefined Japanese sugar usually sold in large, dark brown chunks. You may be able to find kurozato in asian specialty stores, but it is very similar to much more commonly-available Muscovado or Barbados sugar, which can be substituted; the result is nearly identical. Chunks of kurozato, in addition to being a cooking ingredient, are also sometimes eaten straight, as a kind of candy.
