If you’re using a hothouse (or English) cucumber, peeling and seeding is not necessary. If using a garden cucumber, then you may want to remove most, or all of the peel. Also, slice the cucumber in half and gently remove the seeds with a spoon. Here, we use a hothouse cucumber so we left the peel mostly intact; we added a little interest by scoring it with a lemon zester (a fork, will work too).
