The real stuff

“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 horseradish". 

-From Eleanor Early, in her 1940 book, A New England Sampler
