For centuries New York was famous for its oysters, which until the early 1900s played such a dominant a role in the city's economy, gastronomy, and ecology that the abundant bivalves were Gotham's most celebrated export, a staple food for the wealthy, the poor, and tourists alike, and the primary natural defense against pollution for the city's congested waterways. Filled with cultural, historical, and culinary insight-along with historic recipes, maps, drawings, and photos-this dynamic narrative sweeps readers from the island hunting ground of the Lenape Indians to the death of the oyster beds and the rise of America's environmentalist movement, from the oyster cellars of the rough-and-tumble Five Points slums to Manhattan's Gilded Age dining chambers.
