Ingredients
For the salad
- 1 oz (28 g) dried wakame seaweed
- 1 small Persian or Japanese cucumber, very thinly sliced
- 2 tablespoons thinly sliced green onion (white and light green parts)
- 1 teaspoon toasted white sesame seeds, plus more for garnish
For the sesame dressing
- 3 tablespoons soy sauce or tamari
- 2 tablespoons rice vinegar
- 1 tablespoon toasted sesame oil
- 1 tablespoon mirin or 2 teaspoons sugar
- 1 teaspoon grated fresh ginger
- 1/2 teaspoon grated garlic (optional)
- 1/4 teaspoon shichimi togarashi or red pepper flakes (optional)
- 1 tablespoon water, to thin if needed
Directions
- Place the dried seaweed in a large bowl, cover with cold water, and soak for 5 to 8 minutes until expanded, tender, and bright green; drain well and gently squeeze out excess water.
- While the seaweed rehydrates, whisk together soy sauce, rice vinegar, sesame oil, mirin, ginger, garlic, and chili flakes in a small bowl until smooth, thinning with a tablespoon of water if the dressing feels too intense.
- Pat the rehydrated seaweed dry with a clean kitchen towel, give it a few rough chops so the strands are bite-sized, and transfer to a serving bowl.
- Add the sliced cucumber and green onion to the bowl and toss lightly to combine.
- Pour the dressing over the salad and toss gently until every strand is glossy and evenly coated.
- Taste and adjust with a pinch of sugar if needed, then sprinkle with toasted sesame seeds.
- Cover and chill for 5 minutes to let the flavors meld, then serve cold or at cool room temperature as a starter or side.
- For the cleanest presentation, plate the salad in a shallow bowl and finish with a few extra sesame seeds and a light drizzle of sesame oil just before serving.
Cook’s Notes
- Do not oversoak the seaweed or it will turn slimy; it should be tender but still have a slight chew.
- Toast sesame seeds in a dry skillet over medium heat for 1 to 2 minutes for the deepest nutty flavor.
- For extra crunch, add 1 tablespoon of toasted crushed peanuts or crispy fried shallots just before serving.
- The dressing keeps separately in a jar for up to 1 week; toss with fresh seaweed right before plating.
- If using fresh seaweed instead of dried, rinse briefly in cold water and skip the soaking step entirely.
