Don't be intimidated to use lye, be cautious, but try it out! It is so worth doing to get that delicious flavor and beautiful brown color. These pretzel rolls are definitely best the day they are baked but they re-crisp beautifully! Simply preheat the oven to 400 F, spritz the rolls with a little water, add extra salt if needed, and bake directly on the rack for 5-10 minutes.
