Salisbury steak is a dish made from a blend of minced beef and other ingredients, which is shaped to resemble a steak, and is usually served with gravy or brown sauce. ... Salisbury steak was invented by an American physician, Dr. J. H. Salisbury (1823–1905), an early proponent of a low-carbohydrate diet for weight loss; the term "Salisbury steak" has been in use in the United States since 1897. ... The dish is popular in the United States, where it is traditionally served with gravy and mashed potatoes or noodles.Does that make Philip Marlowe a closet health nut? (Come to think of it, he never seems to eat carbohydrates other than toast at breakfast.)
The book was The Long Goodbye and Marlowe balances the health food with a few gimlets here and there, at least one with orange instead of lime. He doesn't like it, of course.
