A pretzel is a type of baked pastry made from dough that is commonly shaped into a knot. The traditional pretzel shape is a distinctive symmetrical form, with the ends of a long strip of dough intertwined and then twisted back onto itself in a particular way (a pretzel loop or pretzel bow). Today, pretzels come in various shapes, textures, and colors, but the original soft pretzel remains one of the most common pretzel types.
