Crisp, delicate, and wonderfully refreshing, this traditional Japanese cucumber salad brings a burst of tangy sweetness to your table. The combination of paper-thin cucumber slices and perfectly balanced rice vinegar dressing creates a light side dish that cleanses your palate and adds a satisfying crunch to any Asian-inspired meal.

In my family's kitchen, this salad has become our go-to side dish during warm summer months. My children, usually hesitant about vegetables, eagerly help slice cucumbers and always ask for extra servings.

Essential Ingredients Selection

  • Japanese or Persian cucumbers: Bring the signature crunch and delicate flavor this salad needs. Their thin skin and minimal seeds make them perfect for absorbing the dressing
  • Rice vinegar: Offers a gentle tanginess that regular vinegar cannot match. Choose unseasoned rice vinegar to control the final flavor
  • Pure cane sugar: Balances the acidity and helps create the characteristic sweet-sour taste. Natural sweeteners can alter the traditional flavor
  • Sea salt: Draws out excess moisture, ensuring your salad stays crisp rather than watery

Creating Your Sunomono

Preparation Phase:
Start by washing your cucumbers thoroughly under cool running water. Examine each cucumber carefully, trimming away any blemishes or soft spots.
Slicing Technique:
Position your knife at a slight angle against the cucumber. Create paper-thin slices, maintaining consistent thickness throughout. Watch your fingers and maintain a steady rhythm for uniform results.
Salt Treatment:
Sprinkle sea salt generously over your cucumber slices. Gently massage the salt into the cucumbers, feeling them become more pliable under your fingertips. Let them rest until they release their natural water.
Dressing Creation:
In a separate bowl, whisk together your rice vinegar and sugar until the crystals completely dissolve. The mixture should feel smooth when you run your finger through it, without any graininess.
Final Assembly:
Squeeze excess moisture from your cucumbers gently but firmly. Pour your prepared dressing over the cucumbers, folding them together with care to ensure even coating.

Growing up in a Japanese household, my grandmother would prepare this salad weekly, teaching me the importance of knife skills and patience in creating the perfect texture.

Perfect Pairings

Serve this refreshing salad alongside grilled mackerel or salmon for a traditional Japanese meal. It also works beautifully as a palate cleanser between courses or as a light lunch topped with cooked shrimp.

Creative Adaptations

Transform this classic recipe by adding thin strips of wakame seaweed for an oceanic twist, or incorporate shredded carrots for extra color and crunch. For a protein boost, top with sesame-crusted tofu or poached chicken breast.

Keeping It Fresh

Store your sunomono in an airtight container in the refrigerator for up to three days. The cucumbers will continue to soften slightly but maintain their pleasant texture. Drain any excess liquid before serving leftover portions.
