1Lightly smack the cucumber five or six times to break it open slightly, but avoid smashing it into mush.
2Cut the cucumber into 10–12 bite-sized pieces at an angle.
3Put the cucumber pieces in a bowl, sprinkle with salt, and toss to coat evenly. Let the cucumber sit for 10 minutes. After 10 minutes, drain off any liquid that has been released.
4Toast sesame seeds in a pan.
5Add the sugar, sesame seeds, black vinegar, and grated garlic to the cucumber pieces. Mix well to combine.
6Transfer the cucumber salad to a serving bowl and garnish with chilli crisp to taste. Serve immediately and enjoy!
