Wash the cucumber and pat dry.
Thinly slice the cucumber crosswise. I prefer to use a vegetable peeler for this step so that I can get the thinnest slice possible. You may also use a knife if you prefer thicker slices. I did not peel the skin off but you may do so if preferred.
Combine salt, ground black pepper, sugar, ginger, and vinegar then mix well. (You may also include the cucumber right away then mix everything together as shown in the photo)
Put-in the sliced cucumber and onion. Refrigerate for 2 hours.
Serve. Share and Enjoy.
