📝 About This Recipe

Sunomono is a quintessential Japanese side dish that embodies the philosophy of 'washoku'—balance, freshness, and simplicity. This light, vinegared salad features paper-thin cucumber slices and delicate wakame seaweed bathed in a sophisticated 'Sanbaizu' dressing. It serves as the perfect palate cleanser, offering a refreshing crunch and a sweet-tangy finish that cuts through rich meals with elegant ease.

🥗 Ingredients

The Vegetables

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

Sanbaizu Dressing

  • 4 tablespoons Rice Vinegar (unseasoned is best for control)
  • 2 tablespoons Granulated Sugar (adjust to your preferred sweetness)
  • 1/2 teaspoon Soy Sauce (usukuchi/light color soy sauce is preferred but regular works)
  • 1/4 teaspoon Salt (to balance the acidity)
  • 1 teaspoon Dashi or Water (adds a hint of umami depth)

Optional Protein & Garnishes

  • 4-6 pieces Cooked Shrimp or Octopus (optional, thinly sliced)
  • 1 teaspoon Toasted White Sesame Seeds (for a nutty crunch)
  • 1 inch Fresh Ginger (peeled and cut into needle-thin strips (shoga))

👨‍🍳 Instructions

  1. 1

    Begin by rehydrating the dried wakame seaweed in a small bowl of cold water. Let it sit for about 5-10 minutes until it becomes soft and expands.

  2. 2

    While the seaweed soaks, wash the cucumbers thoroughly. If using English cucumbers, you may want to peel alternating strips for a decorative look, but Japanese/Persian cucumbers have thin enough skins to leave intact.

  3. 3

    Using a mandoline or a very sharp knife, slice the cucumbers into paper-thin rounds. Consistency is key for a professional texture.

  4. 4

    Place the sliced cucumbers in a bowl and sprinkle with 1/2 teaspoon of salt. Toss gently with your hands and let sit for 5-10 minutes. This draws out the water so the salad doesn't become soggy.

  5. 5

    In a small mixing bowl, whisk together the rice vinegar, sugar, soy sauce, salt, and dashi until the sugar is completely dissolved.

  6. 6

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

  7. 7

    Return to the cucumbers. You will notice they have released a significant amount of liquid. Take a handful of cucumbers and squeeze them firmly over the sink to remove as much moisture as possible.

  8. 8

    Place the 'dry' squeezed cucumbers and the wakame into a clean mixing bowl.

  9. 9

    If using shrimp or octopus, add them to the bowl now.

  10. 10

    Pour the prepared Sanbaizu dressing over the cucumber mixture and toss gently to ensure everything is well coated.

  11. 11

    For the best flavor, let the salad marinate in the refrigerator for at least 10 minutes before serving, though it is best enjoyed shortly after making.

  12. 12

    To serve, mound the salad into small individual bowls, piling it high for an elegant presentation.

  13. 13

    Garnish with a sprinkle of toasted sesame seeds and a few needles of fresh ginger on top for a bright, aromatic finish.

💡 Chef's Tips

Always use Japanese, Persian, or English cucumbers; standard slicing cucumbers have seeds that are too large and skins that are too thick. Don't skip the salt-and-squeeze step! Removing the water from the cucumbers is what keeps the salad crunchy and prevents the dressing from being diluted. If you don't have dashi, a tiny pinch of dashi powder mixed with a teaspoon of water works perfectly for that authentic savory depth. For a vegan version, ensure your dashi is 'kombu dashi' (made from kelp) rather than bonito-based. Serve in small, chilled ceramic bowls to maintain the refreshing temperature of the dish.

🍽️ Serving Suggestions

Pair with Tonkatsu (breaded pork cutlet) or Tempura to provide a bright acidic contrast to the fried elements. Serve alongside a bowl of steamed white rice and Miso soup for a traditional 'Teishoku' style meal. Accompany with grilled mackerel (Saba Shioyaki) for a healthy, protein-rich lunch. Pair with a glass of chilled, dry Sake or a light Japanese lager to complement the vinegared dressing.
