软蝴蝶饼的制作
A pretzel is a type of European-descended baked good made from dough in soft and hard varieties and savory or sweet flavors often in a unique knot-like shapes. The archetypal pretzel shape is a distinctive symmetrical looped form, whereby the ends of a long strip of dough are intertwined or brought together and then twisted back onto itself in a certain way ("a pretzel loop"). However, some varieties are instead made in a more plain stick or rod shape. For seasoning and decoration glazes of lye or sugar, coarse or fine salt or sugar, various seeds and nuts can be used. Larger pretzels are typically consumed singly while small pretzels are served in multiples. Pretzels as a food are associated with different backgrounds, cultural purposes and ingredients that include a variety of glazes and coatings. Pretzels made of sour or yeast dough are assumed to be of Christian Medieval European origin. Today, they are still used in southern Germany and adjoining German-speaking regions on Christian holidays and in local customs.
