"The common or harbour Porpoise of the North Atlantic and Pacific was once considered a delicacy in this country, as are other Cetaceans in other lands at the present day. It formed a royal dish even so recently as the time of Henry VIII. The sauce recommended by Dr. Caius for the "fish" was made of crumbs of fine bread, vinegar and sugar. Considered to be a fish, it was allowed to be eaten on fast days."
