Pane carasau is a traditional flatbread from Sardinia. It is thin and crisp, usually in the form of a dish half a meter wide. It is made by taking baked flat bread (made of durum wheat flour, salt, yeast, and water), then separating it into two sheets which are baked again. The recipe is very ancient and was conceived for shepherds, who used to stay far from home for months at a time. Pane carasau can last up to one year if it is kept dry. The bread can be eaten either dry or wet (with water, wine, or sauces).
