This is a food book with a difference. Instead of talking about the different kinds of Indian cuisines, Colleen Taylor Sen sets out to document Indian food through history, something which no one has done before. She traces Indian food through the Vedas, pointing out that alcohol was frowned upon, though other intoxicants like som ras were used for religious rites. Since then soma has vanished from Indian botany and remains an unidentified ingredient. The book is peppered with similar interesting titbits focussing mainly on spices which Sen sees as the connecting thread between the vast variety of Indian food.
