Lychee is a tropical fruit native to southern China. It has a round or oval shape and a thin, rough skin that ranges in color from pink to red when ripe. The flesh of the fruit is white or pale pink and has a juicy, slightly sweet and tangy flavor. It surrounds a single, large seed in the center. Lychee is often eaten fresh or used to make desserts, such as ice cream and smoothies. It is also a good source of vitamin C and other nutrients. When ripe, the fruit will be firm to the touch and have a slightly sweet aroma. It can be stored at room temperature until it is ripe, and then refrigerated until it is ready to be eaten.
