Winter melon, scientifically called Benincasa hispida, is also commonly called the wax gourd, the ash gourd, white gourd, and the winter gourd. Its seasonal name probably comes from the fact that while grown during the summer and autumn, it can be stored and eaten during the winter months. Mature winter melon has a very mild taste, while the immature fruit is sweet.
What It Looks Like
Winter melon is a large fruit grown in warm climates that can grow beyond one foot long and weigh over 40 pounds. It resembles a large watermelon with its oblong shape and dark-green, waxy skin. Unlike a watermelon, the inside of the flesh and seeds are white, it is tasteless, and it cannot be eaten raw. When it is immature, the outside of the fruit is fuzzy. Once it matures, it loses its hair and gets a waxy coating.
How It's Cooked
Cubed or sliced, winter melon can be steamed, simmered, braised, or parboiled and added to stir-fries. Best used in soups, you can season this rather mild and bland melon with strong spices and herbs. Winter melon is suitable for pickling and may be diced and candied. Whole winter melons will keep in a cool place for months and likely up to a year.
Winter melons absorb the flavors of the ingredients it is cooked with. A famous Chinese dish is winter melon soup, where slices of the melon are simmered in a broth with Chinese dried mushrooms, ham, and seasonings. In a popular banquet version of the dish, winter melon serves as a cooking vessel, main ingredient, and the serving dish. The soup is steamed inside a whole winter melon and served that way at the table.
Winter melon is also used in sweets, such as Chinese wife cake, also called sweetheart cake, and the Indian treat petha, and in curries.
In the Philippines, it is candied and called kundol. It is used as a pastry filling for bakpia Chinese sweet rolls or hopia sweet mooncakes in the Philippines.
Where to Find It
Although winter melon is popular in China, it was originally grown in Egypt. It was introduced to Europe during the Renaissance. Today, this melon is cultivated throughout the world. It is grown in Europe, Asia, the Americas, and Australia.
Winter melon can be found in most Asian supermarkets. Whole winter melon may be available while in season, but it is easier to find cut pieces. The melon slices will last for a couple of days if placed in a plastic bag in the crisper section of the refrigerator.
Significance in Chinese Culture
Winter melon is used in Chinese medicine as an herbal treatment for mild urinary tract problems. It is high in Vitamin B and in dietary fiber.
According to Chinese medicine, foods have a thermal property—warming, cooling, or neutral. Winter melon is considered to be a yin or cooling food. In addition to counteracting urinary problems, yin foods are a good balance against fever, swelling, high blood pressure, constipation, among other conditions.
