Prezel lye

General information

Pretzel lye is used in the production of lye pastries. Lye pastry is a special type of usually smaller pastry in which the dough pieces are dipped in caustic soda solution before baking. In commercial production, this is limited to a maximum 4% concentration of caustic solution. The caustic solution reacts with the gluten of the dough and releases amino acids. The amino acids enter a Maillard reaction with the sugars. This creates the typical shiny brown surface during baking and gives the pastry its special, strong taste. The lye only remains on the dough surface and does not penetrate into the dough.
