A lye pretzel is a type of pretzel that is traditionally made by dipping the dough in a solution of food-grade lye before baking. This process gives the pretzel its distinctive dark brown color and unique flavor. The lye reacts with the dough, creating a shiny crust that is both chewy and crisp. Lye pretzels are often enjoyed as a snack or appetizer and can be found in various forms, including soft pretzels and pretzel bites. They are commonly served with mustard or cheese dip and are popular at fairs, sporting events, and bakeries.
