Sunomono (Japanese Cucumber Salad)
A classic Japanese side dish, Sunomono is a light and refreshing cucumber salad featuring thinly sliced cucumbers and rehydrated wakame seaweed, all tossed in a delicate sweet and sour rice vinegar dressing.
For 4 servings
**Prepare Cucumber:** Wash the Japanese cucumbers thoroughly. Using a mandoline or a very sharp knife, slice the cucumbers into very thin rounds (about 1-2 mm thick). Place the slices in a large bowl, sprinkle with 1/2 teaspoon of salt, and toss gently to coat. Let them sit for 10-15 minutes to draw out excess water.
**Rehydrate Wakame:** While the cucumbers are resting, place the dried wakame in a small bowl and cover with cold water. Let it soak for 5-7 minutes until fully rehydrated and tender. Drain the wakame well and gently squeeze out any excess water. If the pieces are large, chop them into bite-sized strips.
**Make the Dressing:** In a separate medium bowl, whisk together the rice vinegar, granulated sugar, and soy sauce until the sugar is completely dissolved. Taste and adjust sweetness or tanginess if desired.
**Squeeze Cucumber:** After 10-15 minutes, the cucumber slices will have released a significant amount of water. Gather handfuls of cucumber slices and firmly squeeze out as much liquid as possible. This step is crucial for a crisp texture and to prevent the salad from becoming watery.
**Combine and Chill:** Add the squeezed cucumber slices and the rehydrated wakame to the bowl with the dressing. Toss gently to ensure all ingredients are well coated.
**Garnish and Serve:** Transfer the sunomono to a serving dish. Sprinkle generously with toasted sesame seeds. For best flavor and crispness, cover and chill in the refrigerator for at least 15-20 minutes before serving.
What to keep in mind.
4 tips from the recipe — small details that make a real difference to the final dish.
- 1**Mandoline for Uniformity:** Using a mandoline slicer ensures consistently thin cucumber slices, which is key for both texture and efficient water extraction.
- 2**Squeeze Thoroughly:** Don't be shy when squeezing the cucumbers; the more water you remove, the crisper your salad will be and the better it will absorb the dressing.
- 3**Adjust Sweetness:** The amount of sugar can be adjusted to your preference. Start with less and add more if you prefer a sweeter dressing.
- 4**Chill for Best Results:** While delicious immediately, chilling the sunomono for at least 15-20 minutes allows the flavors to meld and enhances its refreshing quality.
