- 1 teaspoon sea salt

How to Make Sunomono (Japanese Cucumber Salad)
- Prep the Cucumbers: Using a mandoline or a sharp knife, thinly slice the Japanese cucumber. Toss the slices with sea salt in a bowl and let them sit for about 3 to 6 minutes. This step helps draw out excess moisture.
- Squeeze Out Excess Moisture: After sitting, gently squeeze the cucumbers to remove any extra moisture. If they taste too salty, rinse them briefly under cold water, but if the saltiness is just right, proceed to the next step.
- Make the Dressing: In a separate bowl, combine the rice wine vinegar, sugar, soy sauce, and toasted sesame seeds. Whisk the mixture until the sugar fully dissolves.
- Combine and Serve: Toss the prepared cucumbers with the dressing until well coated. Serve immediately or chill in the refrigerator for a few minutes to enhance the flavors. Enjoy!
Tips for Success
- Uniform Slices: Use a mandoline for even, thin slices to ensure consistent texture and flavor throughout the salad.
- Taste and Adjust: After mixing the cucumbers with the dressing, taste and adjust the ingredients according to your prefered sweetness or tanginess.
- Chill for Flavor: Allowing the salad to sit in the refrigerator for a short period can deepen the flavor and enhance the overall experience.
- Serving Temperature: Sunomono can be served cold or at room temperature, depending on your preference.
Easy Variations
- Add Carrots: Incorporate julienned carrots for added color and crunch.
- Add Protein: Toss in some cooked shrimp or tofu for a heartier salad.
- Spice It Up: Add a pinch of red pepper flakes for a mild kick.

Storage and Reheating
- Refrigerator Storage: Store leftovers in an airtight container in the refrigerator for up to 2 days. The cucumbers may become softer over time, so it’s best enjoyed fresh.
- Freezer Storage: Freezing is not recommended, as the texture of the cucumbers will deteriorate when thawed.
- Best Serving Temperature: For the best experience, serve cold or at room temperature directly after preparation.
Common Mistakes to Avoid
- Salting Too Long: Avoid letting the cucumbers sit too long with salt, as they may become overly salty or mushy.
- Not Squeezing Enough Moisture: Failing to squeeze out excess moisture can result in a watery salad; ensure this step is executed well.
- Mistiming the Dressing: Add the dressing just before serving to keep cucumbers crisp. Mixing in advance can lead to soggy cucumbers.
