Atul Kochhar's books - he's written 3 I think, the latest one being 'Fish: Indian style'; and the others called something like 'Indian Essence' and 'Simple Indian'.
Atul runs a great restaurant in London called Benares, he holds a Michelin star and the food is absolutely amazing. He has lightened a lot of the sauces and the flavour combinations are incredible.
Benares Restaurant and Bar, Mayfair, London
He doesn't 'do' take-away style indian foods, though!
