Fold the dough over and pinch the seam to seal. Lightly roll to smooth out the seam and place seam side down on a baking sheet lined with parchment paper. Repeat with remaining dough.
Prepare the water bath by mixing hot water with baking soda in a bowl. Dip the pretzel logs into the mixture and place them back on the baking sheet. Top with pretzel salt and bake for 8-10 minutes.
