📝 About This Recipe

A cornerstone of the Izakaya experience, Sunomono is a refreshing, palate-cleansing salad that balances the sharp brightness of rice vinegar with the delicate sweetness of mirin. This classic dish features paper-thin cucumber slices and briny wakame seaweed, offering a satisfying crunch and a cooling sensation that perfectly offsets fried or fatty main courses. It is a masterclass in Japanese simplicity, focusing on the quality of ingredients and the precision of the knife work.

🥗 Ingredients

The Vegetables

  • 2 large Japanese or Persian Cucumbers (thinly sliced into translucent rounds)
  • 1/2 teaspoon Sea Salt (for drawing out moisture)
  • 1 tablespoon Dried Wakame Seaweed (will expand significantly when rehydrated)

The Sanbaizu Dressing

  • 4 tablespoons Rice Vinegar (use high-quality unseasoned vinegar)
  • 2 tablespoons Granulated Sugar (adjust slightly to your preferred sweetness)
  • 1/2 teaspoon Soy Sauce (light soy sauce preferred to keep the color bright)
  • 1 teaspoon Mirin (adds a subtle shine and depth)
  • 1 tablespoon Dashi Stock (or water, to mellow the acidity)

Proteins and Garnishes

  • 1/2 cup Boiled Octopus (Tako) or Cooked Shrimp (optional, thinly sliced)
  • 1 teaspoon Toasted White Sesame Seeds (for a nutty crunch)
  • 1 inch piece Fresh Ginger (cut into needle-thin julienne (shoga))
  • 1 pinch Dried Bonito Flakes (Katsuobushi) (optional garnish for umami)

👨‍🍳 Instructions

  1. 1

    Place the dried wakame seaweed in a small bowl of lukewarm water. Let it soak for about 5-10 minutes until fully expanded and tender.

  2. 2

    While the seaweed soaks, wash the cucumbers thoroughly. Use a mandoline slicer or a very sharp chef's knife to slice the cucumbers into paper-thin rounds, approximately 1-2mm thick.

  3. 3

    Place the sliced cucumbers in a bowl and sprinkle with 1/2 teaspoon of sea salt. Toss gently with your hands to coat every slice.

  4. 4

    Let the salted cucumbers sit for 5-10 minutes. The salt will draw out excess water, which prevents the salad from becoming soggy and ensures a crunchier texture.

  5. 5

    In a small mixing bowl, whisk together the rice vinegar, sugar, soy sauce, mirin, and dashi until the sugar is completely dissolved. This is your 'Sanbaizu' dressing.

  6. 6

    Drain the rehydrated wakame seaweed and squeeze it firmly with your hands to remove all excess water. If the pieces are very large, give them a rough chop.

  7. 7

    Gently squeeze the salted cucumbers to remove the liquid. Be firm but careful not to bruise or break the delicate slices. Discard the cucumber water.

  8. 8

    If using octopus or shrimp, slice them into bite-sized pieces that match the scale of the cucumber slices.

  9. 9

    In a medium bowl, combine the squeezed cucumbers and the drained wakame seaweed.

  10. 10

    Pour the Sanbaizu dressing over the cucumber and seaweed mixture. Toss lightly to ensure everything is evenly coated.

  11. 11

    Divide the salad into small individual serving bowls, piling the ingredients high in the center for an elegant Japanese presentation.

  12. 12

    Garnish each bowl with a sprinkle of toasted sesame seeds, a few needles of fresh ginger, and optional bonito flakes.

  13. 13

    Serve immediately to maintain the crisp texture, or chill in the refrigerator for 15 minutes to let the flavors meld slightly.

💡 Chef's Tips

Use Japanese or Persian cucumbers as they have thinner skins and fewer seeds than English or garden cucumbers. Don't skip the salting and squeezing step; this is the secret to the signature 'crunch' and prevents the dressing from being diluted. If you don't have dashi, a tiny pinch of dashi powder mixed into the vinegar works wonders for an authentic umami boost. For a beautiful visual variation, use a vegetable peeler to peel alternating strips of skin off the cucumber before slicing to create a striped pattern. Always use unseasoned rice vinegar so you can control the sugar and salt levels yourself.

🍽️ Serving Suggestions

Pair with fatty grilled meats like Yakitori or Wagyu beef to cut through the richness. Serve as a side to a bowl of hot Miso Ramen or Udon noodles. Enjoy alongside a glass of chilled Junmai Ginjo Sake or a crisp Japanese lager. Include as part of a traditional Bento lunch with grilled salmon and steamed rice. Combine with other small Izakaya plates like Edamame and Agedashi Tofu for a tapas-style meal.
