These turned out pretty tasty. They're fairly delicate when boiling. The dough flavor is somewhat plain, though the soda, salt, and mustard bring plenty of flavor; I'd like to come back to these with sourdough.
Traditional pretzels aren't boiled. A cool (but caustic) solution of lye in water is the way. It doesn't take much, just add lye to water and not water to lye since it's exothermic.
