Ingredients Breakdown

Yield: Serves 4 as a side dish

Main Ingredient

• 5 mini cucumbers, or 2–3 regular cucumbers (about 4 cups when sliced)

Seasoning & Dressing

• 1 teaspoon salt – for drawing out excess water and seasoning cucumbers
• 1.5 teaspoons soy sauce – adds umami depth
• 1 teaspoon minced garlic – fresh for sharpness and aroma
• 3 tablespoons rice vinegar – for a clean, tangy flavor
• 2–3 teaspoons chili oil – adjust to taste for heat level
• 3 teaspoons sugar – balances the vinegar and spice
• 1 teaspoon sesame oil – for rich, nutty fragrance
• 2 teaspoons sesame seeds (optional) – for texture and garnish
• 3 tablespoons green onions, diced (optional) – for freshness and mild sharpness

Tools & Equipment Needed

• Cutting board and chef’s knife
• Large mixing bowl
• Measuring spoons
• Small spoon or whisk (for mixing dressing)
• Colander (for draining salted cucumbers)

Step-by-Step Instructions

1. Prepare the Cucumbers
   • Wash cucumbers thoroughly. Slice mini cucumbers into thin rounds or half-moons, depending on your preference. For regular cucumbers, slice lengthwise and remove seeds if desired before cutting into half-moons.
2. Salt and Drain
   • Place cucumber slices in a mixing bowl and sprinkle with salt. Toss well to coat evenly.
   • Let them sit for about 5 minutes. This step draws out excess moisture, ensuring your salad stays crisp and doesn’t water down the dressing.
3. Mix the Dressing
   • In a small bowl, combine soy sauce, minced garlic, rice vinegar, chili oil, sugar, sesame oil, and sesame seeds (if using). Stir until sugar dissolves completely.
4. Combine Cucumbers and Dressing
   • Drain any liquid released from the cucumbers and gently pat them dry with a clean kitchen towel or paper towel.
   • Pour the dressing over the cucumbers and toss gently to coat every slice.
5. Add Garnish and Serve
   • Sprinkle with diced green onions if desired. Serve immediately for a fresh, crunchy texture or chill for 15–30 minutes to let the flavors meld.

Tips & Variations

• Adjusting Spice: If you prefer a milder salad, reduce the chili oil to 1 teaspoon or substitute with a mild chili powder. For more heat, add a pinch of Korean gochugaru (red chili flakes).
• Make it Sweeter: Increase sugar slightly for a sweeter flavor profile.
• Vinegar Swap: Use apple cider vinegar or white wine vinegar for a slightly different tang.
• Add Fresh Herbs: Cilantro or Thai basil can add a new layer of freshness.
• Make it a Meal: Toss in cooked shrimp or tofu for extra protein.

• Creamy Twist: Add a spoonful of mayonnaise for a creamy-spicy cucumber salad.
• Kimchi-Style: Add a splash of fish sauce and let the cucumbers ferment for a few hours for a quick kimchi-inspired side.

Ingredient Spotlight: Chili Oil

Chili oil is the backbone of this salad’s mild heat and rich flavor.

• Selecting: Look for chili oil with both infused oil and chili flakes for more texture and flavor.
• Storing: Keep it sealed in a cool, dark place or refrigerate if homemade.
• Boosting Flavor: Add a splash of the oil over grilled meats, noodles, or dumplings for extra depth.

Pro Cooking Tips

• Slice cucumbers evenly so they absorb the dressing at the same rate.
• Salt cucumbers briefly — too long and they lose too much crunch.
• If using regular cucumbers, scrape out the seeds for a cleaner bite.

Storage & Freezing Guide

• Refrigerator: Best eaten within 24 hours. After that, cucumbers lose crispness.
• Freezing: Not recommended — cucumbers become mushy when thawed.
