Dua is a Vietnamese word for pineapple. Pineapple plants are widely grown in Vietnam and also in some Southeast Asian countries, like the Philippines. The peak ripening time for this tropical fruit coincides with summer when the hours of sunshine are longer. People in southern Vietnam usually call this tropical fruit trai thom (fragrant fruit), which is literally a precise quote for the fruit since anyone who takes their first bite can surely notice the strong sweet smell. In Vietnam, pineapples are processed into different products such as canned pineapple, pineapple liquor, sweet preserved pineapple liquor, and sweet preserved pineapple. There is also a special juicy drink that exists only in pineapple growing areas in Vietnam. Growers press the fruit into a juice which is then mixed with the yoke of a hen's egg before being thoroughly stirred together to become a muddy drink. The drink is said to be very sweet, creamy, and nutritious
