Cut the cucumber

• Place the cucumber between two chopsticks and make straight vertical cuts on one side.
• Flip the cucumber over and make diagonal cuts on the other side.

Salt and drain

• Sprinkle the cucumber with salt and rub it in.
• Let it sit so the excess water drains, then discard the liquid.

Make the dressing

• Mix the garlic, soy sauce, black vinegar, sesame oil and sugar in a bowl.
• Stir in the chili oil and toasted sesame seeds.

Toss and serve

• Pour the dressing over the cucumber and toss well.
• Serve immediately, or chill briefly before serving.
