👉 Papaloapan is a type of papaya tree in the family Rutaceae, native to Southeast Asia and South America. It has large, flat leaves that are typically up to three times as long as its fruit diameter, which can range from 20 to 60 centimeters. The fruit consists of a hard, black inner shell covered with white papayas and a white outer shell, both of which are often used in traditional Southeast Asian cooking.
