You must buy a book called

The Ultimate Low Fat Indian Cookery Book

from the Oxford Book shop which is near the church in the middle of road near to the Osbourne Resort in Calangute North Goa. They will get it for you on order in about 5 days. It is the best Indain Cookery book I have ever used and I am a qualified Indian chef (City and Guilds qualified - the first one ever to take and pass the City and Guild exam).
