Chappan kaddu is a summer crop. Immature fruits are picked before the seeds and skin become hardened and used as vegetables.

Fresh fruits are widely available in the South-East Asian markets around the year. Chappan squash can be easily bruised owing to its smooth, delicate skin and should be handled with care. Farmers generally pack them in protective cardboard boxes to markets to protect their skin.

A good chappan squash should be smooth and of average size, having fine skin, and sweet tender flesh. The hardness of skin and seeds and wanting of flavor denote inferior quality and over-ripeness.
