Description
The German pretzel lye‑dip baking technique uses a brief alkaline bath to lower surface pH, accelerating Maillard browning and caramelization during high‑temperature baking.
Technical
A 0.5–1.0 % sodium hydroxide solution briefly immerses the dough, raising surface pH to ≈12.5–13. This alkaline environment deprotonates amino groups, enabling the Maillard reaction with reducing sugars at 220 °C. The resulting melanoidins give the characteristic dark crust and chewy crumb while the high temperature also drives caramelization of surface sugars.
