“There is a terrible pink mixture (with tomatoes in it and herbs) called Manhattan Clam Chowder that is only a vegetable soup, and not to be confused with New England Clam Chowder, nor spoken of in the same breath. Tomatoes and clams have no more affinity than ice cream and horse radish. It is a sacrilege to wed bivalves with bay leaves, and only a degraded cook would do such a thing.’’

— Eleanor Early, in A New England Sampler (1940)
