how did pretzels get their shape
Pretzels originated in Europe, possibly among monks in the Early Middle Ages. The traditional pretzel shape is a distinctive nonsymmetrical form, with the ends of a long strip of dough intertwined and then twisted back into itself in a certain way (a pretzel loop). In the 2010s, pretzels come in a range of different shapes. Salt is the most common seasoning for pretzels, complementing the washing soda or lye treatment that gives pretzels their traditional skin and flavor through the Maillard reaction; other seasonings include various cheeses, sugars, chocolate, glazes, seeds, or nuts.
