How to make Spicy Korean Cucumber Salad

Step 1: Slice the Cucumbers

Wash the cucumbers thoroughly and slice them into thin rounds or diagonal pieces about ¼-inch thick.

Step 2: Salt the Cucumbers

Place the cucumber slices in a bowl and sprinkle with salt. Toss well and let them rest for 10-15 minutes.

This process removes excess moisture and helps keep the cucumbers crunchy.

In another bowl, combine:

• Gochugaru
• Garlic
• Soy sauce
• Rice vinegar
• Sugar
• Sesame oil

Mix until well combined.

Step 5: Combine Everything

Add the cucumbers to the dressing and toss until evenly coated.

Step 6: Garnish

Add:

• Sesame seeds
• Green onions

Mix gently.

Step 7: Chill

For the best flavor, refrigerate for 10-20 minutes before serving.

Serve cold.
