A papaya is a sweet tropical fruit with small, black seeds at the center. Most people eat papayas raw when the fruit is soft and ripe, although some find the smell of a perfectly ripe papaya to be terrible. Many Southeast Asian and South American cuisines include raw and cooked papaya, as well as green papaya and even the leaves of the papaya tree. Papayas are also called pawpaws, which gets a bit confusing since there's a totally different North American fruit also called a pawpaw.
