Creating your Spicy Korean Cucumber Salad is straightforward if you follow these simple steps:

1. Prepare the Cucumbers: Slice the cucumbers thinly. If using Korean cucumbers, you can leave the skin on for added color and crunch. For English cucumbers, you may want to peel them if they have a waxy skin.

2. Salt the Cucumbers: Place the sliced cucumbers in a bowl and sprinkle with salt. Let them sit for about 10 minutes to draw out excess moisture.

3. Make the Dressing: In a small mixing bowl, combine gochugaru, sugar, soy sauce, rice vinegar, sesame oil, and minced garlic. Mix well until the sugar dissolves.

4. Drain and Rinse: After 10 minutes, drain any liquid released from the cucumbers. Rinse them under cold water to remove excess salt and pat dry.

5. Combine: Add the cucumbers to the dressing mixture. Toss everything together until the cucumbers are well coated.

6. Garnish: Transfer the salad to a serving bowl and sprinkle with sliced green onions and sesame seeds.

7. Chill: For optimal flavor, let the salad chill in the refrigerator for 20-30 minutes before serving.

8. Serve: Enjoy your Spicy Korean Cucumber Salad as a fresh side dish!
