the.com/pretzel roll

means A dinner roll that's been given the pretzel treatment — dipped or washed in a lye or baking-soda solution before baking, which gives it that deep mahogany crust, chewy bite, and distinct salty-savory flavor.

from Rooted in the same tradition as the pretzel itself, likely born in medieval European monasteries, where bakers twisted dough into shapes and dipped it in an alkaline bath (historically lye, now often food-grade or a baking-soda stand-in) before baking — a process called 'lauging' that caramelizes the crust into that signature dark, glossy finish. The pretzel roll is simply that same lye-bath logic applied to an ordinary roll shape instead of the knotted pretzel twist, a more modern bakery-case invention riding on centuries-old technique.
