Preheat the oven to 450 degrees F (230 degrees C). Lightly grease a baking sheet or line with foil.

Stir together water and baking soda in a large saucepan. Bring to a boil.

Turn dough out onto a lightly floured surface. Roll into a 10x12-inch rectangle. Cut dough into twelve 1-inch strips. Wrap each strip tightly around a bratwurst in a spiral, pinching edges to seal and leaving about 1/2 inch of bratwurst peeking out of each end.

Add 3 wrapped bratwurst at a time to the boiling water. Boil for about 30 seconds. Transfer bratwurst to the prepared baking sheet. Sprinkle with salt. Repeat with remaining wrapped bratwurst.
