Papaya is a fruit with yellow-orange flesh covered with a thin green outer skin that turns orange or red when the fruit is almost fully ripe. If it has not been cut open, the papaya will not emit any smell. However, when the skin is peeled and cut open to reveal the flesh, the papaya will emit a sweet aroma. In addition to people liking to eat ripe papaya as a snack, papaya is also used in many Thai dishes, especially Somtam, a popular and well-known dish that is unique to Thailand.
