The story goes that someone from Audincourt in the Franche Comté recommended turnip-eating to Napoleon’s armies, earning the good folks of that region the eternal nickname of turnip-eaters, or Croque-Raves.
They do use their turnips to make raves salées (coarsely grated, sautéed in duck or goose fat) to prepare a dish similar to choucroute garnie with the local Saucisse de Montbéliard, saucisses de Strasbourg, bacon, potatoes etc. And like sauerkraut, you can buy your raves salées ready made in regional supermarkets.
