Wash the cucumber and grate it using the large holes on a box grater.
Place the grated cucumber in a strainer or cheesecloth and let it sit while you prepare the other ingredients.
In a blender, combine the juice of 1/2 lemon, 2 chadon beni leaves, 1 scotch bonnet pepper, 1 clove garlic, 1/2 teaspoon salt, and 1/4 teaspoon black pepper. Blend until smooth.
Squeeze out any excess liquid from the grated cucumber and transfer it to a mixing bowl.
Pour the blended mixture over the cucumber and stir to combine.
Taste and adjust salt or pepper if needed. Serve immediately or refrigerate.
