Passion fruit is a tropical fruit native to South America. It has a round or oval shape and a thin, wrinkled skin that ranges in color from yellow to dark purple when ripe. The flesh of the fruit is juicy and has a tart, slightly sweet flavor. It surrounds a large number of small seeds in the center. Passion fruit is often eaten fresh or used to make juices, jams, and desserts. It is also a good source of vitamins and minerals, including vitamin C, potassium, and iron. When ripe, the fruit will be slightly soft 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.
