Japanese Cucumber Salad (Sunomono)

Method

1. Salt the cucumber slices in a bowl and let sit for 10 minutes. The salt draws water out through osmosis, concentrating the cucumber's flavor and creating a drier surface that absorbs the dressing. Squeeze the slices gently to press out excess water.

2. Make the dressing by whisking rice vinegar, sugar, soy sauce, and sesame oil until the sugar dissolves. The balance should be sweet-tart with a subtle savory depth from the soy and nuttiness from the sesame.

3. Toss the squeezed cucumbers with the dressing until evenly coated. Top with toasted sesame seeds and sliced scallion. Serve chilled.

   Toss gently but thoroughly to coat every piece evenly. The goal is uniform seasoning and sauce distribution without breaking delicate ingredients.

Equipment

• Mandoline or sharp knife (paper-thin slices are essential) Recommended: Victorinox Fibrox Pro 8-Inch Chef's Knife · Also good: Victorinox Fibrox Pro 8-Inch Chef's Knife
• Mixing bowls Recommended: Vollrath Stainless Steel Mixing Bowls Set
• Colander (for salting and draining) Recommended: OXO Good Grips 5-Quart Stainless Steel Colander
• Small saucepan (for heating the dressing) Recommended: Cuisinart Chef's Classic 3-Quart Saucepan
• Clean kitchen towel (for squeezing moisture from cucumbers)

Chef Notes

• The most important thing: Salt the cucumber slices and let them sit for 10 minutes, then squeeze out the excess water. This removes moisture that would dilute the dressing and concentrates the cucumber's flavor. The slices should be limp and pliable after squeezing.
• Slice as thin as possible — a mandoline is ideal. Paper-thin slices absorb the dressing and have a delicate, silky texture that thick slices can't match.
• This is a staple side dish in Japanese cuisine — refreshing, palate-cleansing, and served alongside sushi, grilled fish, and rice bowls.
• The dressing should be sweet-tart with a subtle sesame nuttiness. Taste and adjust the sugar-vinegar balance.
• Serve chilled. This salad is best cold.

Common Substitutions

Ingredient	Substitution	Notes
Soy sauce	Tamari or coconut aminos	Tamari is gluten-free. Coconut aminos are lower sodium.
Rice vinegar	White wine vinegar or apple cider vinegar	Both are milder than distilled white.
Sesame oil	Toasted walnut oil or peanut oil	Walnut oil is nuttier. Peanut oil for frying.
Sugar	Coconut sugar or maple syrup	Coconut sugar is 1:1. Maple: reduce liquid slightly.
Scallions	Chives or thinly sliced leek greens	Chives are milder. Leek greens are closest in flavor.

What You're Practicing

Sunomono teaches you about Japanese vinegar-based preparations (sunomono literally means "vinegared things"). The same sweet rice vinegar dressing is used for seaweed salad, octopus sunomono, and pickled vegetables. Visit Vinaigrettes for more on vinegar-based dressings.

Salting and squeezing vegetables to remove moisture is a universal technique — from Japanese sunomono to Korean muchim to Turkish cacik. Understanding osmosis gives you control over texture and flavor concentration.
