Sunomono is a classic Japanese vinegar salad that serves as a light, palate-cleansing side dish or appetizer. Thinly sliced cucumbers are briefly salted to draw out excess moisture, then tossed with rehydrated wakame seaweed in a tangy rice vinegar dressing balanced with soy sauce, a touch of sugar, and toasted sesame. Serve chilled alongside grilled fish, rice bowls, or any rich main course.

Ingredients
For the salad
- 2 Japanese or Persian cucumbers (about 12 oz / 340 g), very thinly sliced
- 1/2 teaspoon fine sea salt
- 2 tablespoons dried wakame seaweed
- 2 tablespoons very thinly sliced sweet onion (optional)
- 2 tablespoons toasted white sesame seeds
For the vinegar dressing
- 1/3 cup unseasoned rice vinegar
- 2 tablespoons soy sauce or tamari
- 1 tablespoon granulated sugar
- 1 teaspoon grated fresh ginger
- 1/2 teaspoon dashi granules (optional)
- 1/8 teaspoon freshly ground white pepper
Directions
- Place the sliced cucumbers in a colander, sprinkle with the salt, toss well, and let stand for 10 minutes to draw out excess water; rinse briefly and pat thoroughly dry with paper towels.
- Meanwhile, place the dried wakame in a small bowl, cover with cool water, and soak for 5 minutes until softened; drain and gently squeeze out any remaining water.
- In a small saucepan over low heat, whisk together the rice vinegar, soy sauce, sugar, ginger, dashi, and white pepper just until the sugar and dashi dissolve, about 1 minute; remove from heat and let cool completely.
- In a mixing bowl, combine the drained cucumbers, rehydrated wakame, and optional sweet onion.
- Pour the cooled vinegar dressing over the cucumbers and toss gently until everything is evenly coated.
- Cover and refrigerate for at least 15 minutes to allow the flavors to meld and the salad to chill through.
- Just before serving, sprinkle the toasted sesame seeds over the top and toss once more.
- Serve cold in small bowls as a refreshing appetizer, side dish, or palate cleanser.
Cook’s Notes
- Salt and drain the cucumbers thoroughly so the dressing isn't watered down and the slices stay crisp.
- For the best texture, use Japanese or Persian cucumbers and slice them paper-thin on a mandoline.
- Adjust the sugar-to-vinegar ratio to taste; add an extra splash of rice vinegar for a sharper tang.
- Add shredded imitation crab (kanikama) or small cooked shrimp to turn this into a heartier appetizer.
- Best enjoyed within 4 hours of dressing; beyond that the cucumbers begin to lose their crunch.
