Even though one book after another repeats this myth, the popularity of spices had nothing to do with disguising the taste of meat or fish that had gone bad. any lord who could afford spices (which were expensive) could easily get fresh meat or fish (which were readily available); and when a cook happened to be stuck with rancid food, the spices he had available could not hide the awful smell or taste. whenever they could, people used the spices that were so popular, they became an expensive necessity: pepper, ginger, sugar, sometimes saffron. only the very rich could afford the luxuries—such as ambergris (which is coughed up by whales and offers a strange, perfumy taste of the sea).
