Hi tempest63,

apart from books borrowed from the library I have two I bought.
Step by Step Guide to Indian Cooking. By Khalid Aziz.
Indian Cookery. By Bay Books Cookery Collection.
I did have "The Curry Secret" Kris Dhillon. But gave it away not long after joining this site..
I found the information at the start of 50 Great Curries of India to be very helpful but only tried the Homestyle basic curry and I added a bit of Onion`s base sauce. Turned out quite nice.. ;D
