This imaginative book tells the history of India and its rulers through their food. It follows the story of curry as it spread from the courts of Delhi to the balti houses of Birmingham.Curry is the product of India's long history of invasion. In the wake of the Mughal conquerors, an army of cooks brought Persian recipes to northern India; in the south, Portugese spice merchants introduced vinegar marinades and the chillies they had recently discovered in the New World; the British soon followed, with their passion for roast meat accompanied by cauliflowers and beans. When these new ingredients were mixed with native spices, they produced these distinctly Indian dishes.
