Ingredients

  • 400 grams Japanese cucumber (~3 Japanese or ~4 Persian cucumbers)
  • 1/2 teaspoon salt
  • 30 grams toasted sesame seeds (~1/4 cup)
  • 1 tablespoon sugar
  • 1/3 cup miso
  • 2 cups dashi
  • 4 servings cooked short-grain rice
  • 5 leaves green shiso (optional, finely julienned)
  • 1 myoga (optional, sliced thinly)
  • Shichimi togarashi (optional)

Instructions

  1. Slice the cucumbers thinly (about 1/16-inch thick) and toss them with the salt to coat evenly. Let this rest for at least 20 minutes while you prepare the soup.
  2. Add the toasted sesame seed to a mortar and use a pestle to coarsely grind them.
  3. Add the sugar and grind it in with the sesame until the mixture looks like damp sand.
  4. Add the miso and grind this into a paste with the other ingredients.
  5. Add about 1/4 of the dashi and combine with the mixture until it's smooth.
  6. Add the remaining dashi and mix together.
  7. You can also do this in a blender or food processor by pulsing the toasted sesame seeds and sugar together before adding the miso and all of the dashi and pulsing until it's free of lumps.
  8. To serve the Hiyajiru, massage the salted cucumbers until they release a lot of liquid and turn translucent.

  9. Use your hands to squeeze out as much water from them as you can and transfer them to a serving bowl.
  10. Top with the soup, add a few ice cubes and garnish with the shiso and myoga. Serve with shichimi togarashi for sprinkling to taste.

  11. For the rice, rinse the freshly cooked (or reheated rice) in cold water to chill and remove any excess starch. Then, drain it and serve in rice bowls.
