This reasonably priced paperback is what I call a kitchen workhorse. One of those books you go back to time and time again for basic techniques and information. It is not a glossy coffee table book with photos to die for - it has no photos at all.
Instead this book talks you through the basic ingredients of Thai cooking - what does what, why you use it and what to substitute if you can't get it. It has a section on growing your own herbs for authentic flavour. It has a chapter on equipment, and cooking techniques. It explains how to get the right balances in flavour. There is a chapter on Thai curry pastes, describing and explaining them all, and even tells you how to jazz up store bought curry pastes. It then takes you to the step by step recipes. These go from a step by step guide to perfect steamed jasmine rice, which not only tells you what to do, but more importantly why, to recipes for perfect pad thai, with tips and important points to remember for instance;
"Cook your pad thai in one or two serves only: too much food in the wok will stew rather than stir-fry and you won't get that lovely `wok' flavour."
This book is almost the Thai cooking version of Nicholas Clee's "Don't Sweat the Aubergine: What Works in the Kitchen and Why"
The reason to buy this book is that it cost's no more than a one meal readymade fancy pack of Thai spices, and you will never need to buy a ready meal again.
