This simple salad is a great palate cleanser and pairs well with a variety of main dishes. It's quick to prepare and requires minimal ingredients, making it an ideal choice for a light and healthy addition to your meal.
Rice vinegar is a key ingredient in this recipe that may not be commonly found in every household. It has a mild, slightly sweet flavor that is essential for achieving the authentic taste of sunomono. If you don't have rice vinegar, you can find it in the Asian foods section of most supermarkets. Toasted sesame seeds add a nutty flavor and a bit of crunch, and they can usually be found in the spice or baking aisle.
Ingredients For Cucumber Sunomono Recipe
Cucumbers: Thinly sliced to create a light and crisp base for the salad.
Rice vinegar: Provides a mild, slightly sweet acidity that is essential for the dressing.

When preparing cucumbers for sunomono, use a mandoline slicer to achieve uniformly thin slices. This ensures even absorption of the vinegar mixture and enhances the overall texture of the dish.

How to Store or Freeze This Recipe
- To store your cucumber sunomono, transfer it to an airtight container. This will help maintain its crispness and prevent it from absorbing other odors in the fridge.
- Place the container in the refrigerator. The cucumber sunomono will stay fresh for up to 3 days. Beyond this period, the cucumbers may start to lose their crunch and the flavors might not be as vibrant.
- If you want to prepare the dish in advance, consider storing the vinegar mixture separately from the cucumbers. Combine them just before serving to ensure maximum freshness and texture.
- Freezing cucumber sunomono is not recommended. The high water content in cucumbers causes them to become mushy and lose their appealing crunch when thawed.
- For a quick refresh, you can add a splash of rice vinegar and a sprinkle of toasted sesame seeds just before serving. This will revive the flavors and add a bit of extra zest to the dish.
- If you have leftover toasted sesame seeds, store them in a cool, dry place in an airtight container. They can be used to garnish other dishes, adding a nutty flavor and crunchy texture.
How to Reheat Leftovers
- Gently drain any excess liquid from the cucumber sunomono to avoid sogginess.
- Place the cucumbers in a microwave-safe dish. Cover with a microwave-safe lid or plastic wrap to retain moisture.
- Heat in the microwave on medium power for 20-30 seconds. Check the temperature and heat in additional 10-second intervals if needed.
- Alternatively, you can reheat the sunomono in a small saucepan over low heat. Stir gently and heat for 1-2 minutes until just warmed through.
- For a refreshing twist, consider serving the cucumber sunomono cold. Simply remove from the refrigerator and let it sit at room temperature for 5-10 minutes before serving.
