I bought this book a few years ago and despite buying / being given other curry cook books, I always go back to this one time and time again. Madhur writes very affectionately about her childhood memories of food in India - it's the type of thing I would normally find very irritating in a cookery book, however I genuinely think it's helped me over the years create some fantastic food from the recipes.
There's a mixture of simple and complex recipes - all of which are pretty amazing. I've learnt to eat Indian food in a completely different way to how you would in a typical restaurant eg you eat the raita's etc with your main course to balance the flavours and heat. The variety of chutneys, accompaniments, vegetable dishes and snacks is vast for such a modestly sized book. Also, Indian food tastes much fresher and far less cloying than the stuff we're normally subjected to in a restaurant. This book has been so influential in our household that we rarely go out for a curry now because they taste so much better at home.
Don't be put off by the fact there's no pictures, it's packed full of useful tips. Also, you will need a food processor and something to grind spices with - apart from this no other special equipment is needed.
A gem of a book - if you have all the modern books, try this one for some lovely Indian home cooking like it used to be!
