Fish, rice and mustard: a delta kitchen of sharp mustard oil and freshwater fish, eaten in courses from bitter to sweet, and ending with some of India's most famous sweets.
Bengal is river country, and the saying goes that fish and rice make a Bengali — maach-bhaat. Mustard grows everywhere, so mustard oil is the cooking fat and ground mustard the great sauce, and a proper meal comes in courses: something bitter first, then dal and fries, vegetables, fish, perhaps meat, a sweet-sour chutney and, at the end, sweets and yoghurt.
Murshidabad was the seat of the Nawabs of Bengal in the eighteenth century, and Calcutta, now Kolkata, grew under the British into the capital of their India until 1911. Both left their mark: rich Mughlai meat dishes on one side, a city of clubs, cabins and street food on the other. Milk split into chhena became the base of Bengal's sweets — some say a technique learned from the Portuguese, though nobody is sure.
Partition in 1947 divided Bengal: the east became East Pakistan and, in 1971, Bangladesh, which shares the same language and much of the same kitchen. Families who crossed westward brought their East Bengal cooking to Kolkata, and the gentle rivalry between Bangals from the east and Ghotis from the west — hilsa against prawn, one football club against another — is still part of the city.
