I got a packet of frozen tinda, from the Indian store. The packet says "punjabi Tinda", which is also a Indian baby pumpkin. Then i looked up the web and wikipedia says -
Tinda,also called Indian round gourd or apple gourd, is an annual vine grown for its immature fruit, a vegetable especially popular in South Asia.This vegetable is cooked in different ways in India, especially in the northern part of India. I heard about this vegetable from a close friend in school and was on the look out for this vegetable. Though i didn't get any fresh ones, these frozen ones turned out equally good.
