Kastu

Kastu, also known askastus or kastu-fruit, is a type of fruit native to Southeast Asia, particularly prevalent in the Philippines and Indonesia. It is a tropical fruit characterized by its distinctive appearance and aroma. The fruit typically grows on trees that can reach considerable heights.

Morphologically, kastu is often described as oval or round, with a leathery rind that can range in color from green to yellow or orange when ripe. The interior of the fruit contains a segmented pulp, which is usually a pale yellow to white color. The pulp is known for its sweet and slightly tangy flavor, often compared to a blend of mango and durian, though it lacks the strong odor of the latter. The seeds are typically large and hard.

Culturally, kastu is a popular fruit in its native regions, often consumed fresh. It is also used in traditional cuisines and beverages. While not widely known internationally, it holds significance within the local agricultural and culinary landscapes. Efforts are being made to preserve and promote its cultivation due to its unique characteristics and potential for wider appreciation. The fruit is a source of vitamins and dietary fiber.
