Ingredient Breakdown: All You Need for This Tasty Salad
- 1 Large Japanese Cucumber
- 1 Teaspoon Sea Salt
- 2 Tablespoons Rice Wine Vinegar
- 1 Tablespoon Sugar
- 1 Teaspoon Soy Sauce
- 1 Teaspoon Toasted Sesame Seeds
Let’s Get Cooking!
Step-by-Step Instructions
Prep the Cucumbers (3-6 minutes): Grab your mandoline ( or a sharp knife if you don’t have one) and slice the cucumber thinly. If you’re using a knife, aim for about 1/8 inch thick slices for the best texture. Toss those beautiful circles (or half-moons, depending on your slicing style) of cucumbers with a generous pinch of salt. Let them sit for about 3 to 6 minutes until they’re glistening and some moisture is released. You’ll know they’re ready when you see those beads of water glistening like diamonds on the surface.
Squeeze and Rinse (2 minutes): Once they have relaxed, take your cucumbers and give them a gentle squeeze to get rid of excess moisture. If they taste too salty for your liking, give them a quick rinse with cold water before gently patting them dry with a paper towel. We’re looking for salty, not woah-this-is-a-brine-level salty!
Make the Dressing (2 minutes): In a separate bowl, combine the rice wine vinegar, sugar, soy sauce, and toasted sesame seeds. Whisk it all together briskly until the sugar has dissolved, just about 30 seconds to a minute. You want it well mixed so every bite gets that tasty dressing. It should smell tangy and a little sweet, almost like a sweet and sour harmony wafting in the air.
Combine and Serve (1-2 minutes): Toss the cucumbers in the dressing, ensuring every slice gets its share. You can serve this immediately, which is my personal favorite, but let it chill in the fridge for about 10 minutes for an even cooler vibe.

And voilà! Your Sunomono is ready. Doesn’t that sound easy? Seriously, I could whip this up anytime, it’s that simple!
