Winter Melon is a popular vegetable in Asian countries. It is native to Japan, Java, China, and India. The fruit of the plant is juicy, fleshy, and contains plenty of seeds inside. The texture of the pulp is crunchy and juicy and it carries nil to slightly acidic taste. Winter melon is cultivated and consumed across South East Asia as a vegetable and also added to desserts and juices.
The technical name of winter melon is Benincasa Hispida and it belongs to the Cucurbitaceae family. It is commonly known as petha, white gourd, white pumpkin, wax gourd, and ash gourd. The plant grows as an extensive trailing or climbing vine, and it can be cultivated on the hills up to 1200 m altitude. Since the plant grows very well in cold weather conditions, it has been named as winter melon.
Immature fruits are fairly hairy and dark green in color. However, the fruit looses the hair as it matures and hence carries a light greenish colour with wax like white coating on it. This coating is harmless for consumption. The waxy white coating also provides it with an extended shelf life, as much as one month in dry and cold conditions.
