Rutabaga is the common American and Canadian term for this plant. It comes from the old Swedish word Rotabagge, meaning simply "root bag". "Swede" is the preferred term used in England, Wales, Australia, New Zealand and many other parts of the world that use British English as a standard. In the U.S., the plant is also known as "Swedish turnip" or "yellow turnip".
In parts of the United Kingdom rutabagas are called swedes. They are regularly eaten mashed as part of the traditional Sunday roast. Often they are boiled together with carrots and served either mashed or pureed with butter and ground pepper. The highly flavoured cooking water is often retained for soup, or as an addition to gravy. Swedes are an essential vegetable component of the traditional Welsh lamb broth called cawl.
