For best results, use an active, bubbly sourdough starter that has been recently fed, since a sluggish starter will lengthen rise times and can make the dough denser. If your kitchen is cool, allow extra time for the bulk rise or place the covered bowl in a slightly warm (but turned off) oven to encourage fermentation. When shaping, avoid adding too much flour to the surface so the ropes grip the counter and roll out more easily, and if the dough springs back, let the pieces rest for 5–10 minutes to relax the gluten. The baking-soda bath is key for traditional pretzel color and flavor, so maintain a gentle simmer rather than a vigorous boil to keep the pretzels from breaking apart. You can adjust the chewiness by boiling slightly longer for a firmer crust or shortening the bath for a softer bite, and for variety, skip the salt and brush the baked pretzels with melted butter and cinnamon sugar for a sweet version.
