Context

“they have no fish, although they are on the shores of the Hellespont, and they are not allowed boiled meats but only roast, which is the food most convenient for soldiers, requiring only that they should light a fire, and not involving the trouble of carrying about pots and pans. True. And I can hardly be mistaken in saying that sweet sauces are nowhere mentioned in Homer. In proscribing them, however, he is not singular; all professional athletes are well aware that a man who is to be in good condition should take nothing of the kind. Yes, he said; and knowing this, they are quite right in not taking them. Then you would not approve of Syracusan dinners, and the refinements of Sicilian cookery? I think not. Nor, if a man is to be in condition, would you allow him to have a Corinthian girl as his fair friend?” source
