Longan is a tropical fruit native to southern China and Southeast Asia. It has a round or oval shape and a thin, brown skin when ripe. The flesh of the fruit is white or pale pink and has a juicy, sweet flavor. It surrounds a single, small seed in the center. Longan is often eaten fresh out of hand. It is also a good source of vitamins and minerals, including vitamin C, potassium, and iron. 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.
