Cut off the stem of the mango and hold the fruit upright, cupping it in the palm of your hand. With the other hand, use a potato peeler to cut away the skin, following the curves of the fruit.

Lay the fruit on its flat end and slice lengthways, working around the flat stone in the middle. Cut the fruit into thin slices as desired.

Stand the mango upright to carve away the remaining flesh surrounding the stone.
