Du du is a Vietnamese word for papaya. In Vietnam, papaya is sold all year round, especially in the south, and is not very expensive. It has a sweet smell and offers various minerals and vitamins, such as vitamin A and C. In the south, one of the popular varieties of papaya is the one with red, thick pulp that has a fragrance but that does not contain much sugar. This species is grown in the Mekong Delta Region and in the area close to the Cambodian border. Another species of papaya available in the south is the one with yellow or orange peel.
Papayas are not as abundant in the north. Because of the colder climate, fruits take a longer time to ripen.
