This Japanese Sunomono Turns Cucumbers Into a Showstopper With Rice Vinegar and Toasted Sesame
Subtle flavor. Sweet‑tart marinade. Bold Asian flair. Recipe inside.
If your idea of a cucumber salad is three ingredients and a shrug, let me introduce you to the breezy Japanese version that actually tastes like something. Sunomono is crisp, cool, and quietly punchy thanks to a rice-vinegar marinade that leans sweet-and-tangy with just enough soy to ground it. It takes about 15 minutes, plays well with anything from grilled fish to roast chicken, and basically tastes like summer behaving itself.
What you need
- Cucumbers — 4 medium (about 400 g)
- Rice vinegar — 2 tbsp
- Soy sauce — 1 tbsp
- Sugar — 1 tsp
- Salt — 1/4 tsp
- White sesame seeds, toasted — 1 tsp
- Fresh ginger, finely grated — 1/2 tsp (optional)
- Nori (dried seaweed) — 1 strip (about 2 g, optional)
How to make it (quick, clean, and extra crisp)
1. Prep the cucumbers. Wash them well, trim the ends, and slice into thin half-moons or long, slender ribbons. Thinner slices take on the marinade faster and keep the salad light and elegant.
2. Salt and rest. Sprinkle the cucumber with the 1/4 tsp salt, toss gently, and let it sit for 5–7 minutes. This pulls out excess water so the texture stays snappy instead of soggy.
3. Build the marinade. In a small bowl, mix rice vinegar, soy sauce, and sugar until the sugar fully dissolves. If you like a little zing, stir in the grated ginger. It adds a clean, peppery lift without hijacking the flavor.
4. Drain and dress. Pour off the liquid the cucumbers released and give them a light squeeze with your hands. Move them to a clean bowl, pour the marinade over, and toss so every piece gets its moment.
5. Marinate briefly. Cover the bowl with plastic wrap and let the salad stand at room temperature for 10–15 minutes. That short rest is exactly how you get a balanced, bright finish.
6. Finish and serve. Right before serving, shower the top with toasted white sesame seeds. If you want a little ocean whisper, slice a strip of nori into fine threads and lightly moisten them with water so they soften, then scatter over the salad.
How to eat it
Serve sunomono chilled as a stand-alone snack or park it next to sushi, maki rolls, grilled or roasted fish, or simple chicken. It is the kind of side that quietly upgrades the whole plate and, yes, very likely becomes your go-to summer garnish.
