Pretzels. These twisted strips of baked dough can be either sweet or savoury, depending on the toppings or flavourings added. Here, salt grains have been added, making this a savoury pretzel. There are a wide range of types and forms of pretzels, and they can range in texture from soft to crisp. These are Bavarian pretzels, photographed in Germany.
