Baking Soda Bath
Immediately after making your dough, prepare your baking soda bath in a large mixing bowl by combining 2 cups of warm water and 2 tablespoons of baking soda. Stir until dissolved and continue to stir regularly while the dough is rising.
Once your dough is finished rising and has doubled in size. Put your ball of dough on a pastry mat and remove a section about 3/4 cup in size. You can break off as large or as small of a piece as you like depending on the pretzel size you want to make. Roll your section of dough into a long 1/2 inch thick string of dough. The length will vary depending on how big you want your pretzel, but the thickness should be no bigger than 1/2 inch in diameter. When rolling the dough, I found it helpful not flouring my work surface and lightly wetting my hands with water (not soaking wet). To get the right shape, roll the dough up and down with your hands, all the while pushing from the center out to get a long and narrow string of dough. That's what worked for me, but you'll find a good rhythm of your own too I'm sure!
Once you have your long string of dough, bring one end to the center, letting it hang slightly over the edge. Then bring your other end over and weave it underneath the first loop to get a pretty knot. Then dip your pretzel into the baking soda bath water, making sure to hold its shape in place. Place it on a well greased cookie sheet, making sure to put them about 1 1/2 inches in between each other. Preheat your oven to 450 degrees and let your pretzels sit for 15-20 minutes before baking to allow for a second rise. Bake for 10 minutes or until golden brown.
Meanwhile, prepare your dipping ingredients. Melt about 4 tablespoons of butter. Then mix your sugar and cinnamon together if you're making cinnamon sugar pretzels. To make an icing glaze to dip your cinnamon sugar pretzels in, combine your powdered sugar and water together in a bowl. Mix until combined and set aside for dipping. When your pretzels are cool enough to handle, generously brush them all over with your melted butter. Then dip in your cinnamon sugar mixture until coated or sprinkle with sea salt. Serve your traditional pretzels with a side of mustard for dipping or serve your cinnamon sugar pretzels with icing.
