Etiquette and manners are all very fine but there is only one rule that matters when it comes to soup, and that’s to do with an accompaniment, bread. Bread and soup go together so well. And the bread you choose will vary depending on the type of soup. But there is one crime so heinous that it should never ever be contemplated. That crime is to put butter or margarine on the bread. It is fine to dip your bread in soup, or to mop up the last soup dregs lurking in the bowl with some bread, but you should never ever put any spread on your bread!
