Cut your cucumber. You can cut it in slices or you can make spirales (like on the photo). To cut you cucumber in slices, take two chopsticks that you place on each side of the cucumber. Start by cutting slices but stop when you hit the chopsticks. Then flip your cucumber on the other side, and cut diagonally. Just as before you stop cutting when you feel the chopsticks. Lightly salt your cucumber and let it rest in the refrigerator for approximately 15-20 minutes.
Grate your garlic cloves.
In a bowl mix the garlic cloves, the rice vinegar, the chili oil, the sesame oil, the cayenne pepper and the sugar.
Grill the sesame seeds in a pan on low heat. Once golden brown, let cool and add to the dressing.
Take your cucumbers out of the refrigerator and rince very well. Make sure all the salt has been washed off.
Add the dressing to your cucumbers and enjoy.
