Parwal ki Mithai-This is very unusual use of a vegetable in a dessert.My husband is very found of this mithai. It is popular in Bihar & West Bengal. Every sweet shop in Calcutta would stock this Mithai but in Delhi it is difficult to find. Whenever we go to Calcutta Dharmesh wants to have "Parwal ki mithai".When I was reading BBC Good Food,I found this recipe in that magazine.I tried this recipe today and it came out very well.
