01 - Combine warm water, yeast, and 1 tablespoon sugar in a large bowl. Let stand for 5 minutes until foamy and activated.
02 - Add melted butter, flour, and salt to the yeast mixture. Stir until a shaggy, sticky dough forms.
03 - Knead by hand on a floured surface or with a stand mixer using the dough hook for 5 to 7 minutes until smooth, elastic, and no longer sticky.
04 - Place dough in a lightly greased bowl, cover with plastic wrap or a clean towel, and let rise in a warm, draft-free area for 1 hour until doubled in size.
05 - Preheat oven to 450°F. Line two baking sheets with parchment paper and set aside.
06 - Bring 10 cups water and baking soda to a rolling boil in a large pot. Reduce heat to maintain a steady simmer.
07 - Turn dough onto a lightly floured surface. Divide into 8 equal pieces. Roll each piece into a 20-inch rope, then form into the classic pretzel shape by twisting ends together and pressing onto the curve.
08 - Carefully lower each pretzel into the simmering baking soda bath for 30 seconds. Remove with a slotted spatula, allowing excess liquid to drain, then transfer to prepared baking sheets.
09 - Bake for 12 to 15 minutes until deep golden brown with a shiny, crisp crust.
10 - Immediately brush hot pretzels generously with melted butter while still warm.
11 - Mix granulated sugar and cinnamon in a shallow bowl. Toss each buttered pretzel in the mixture, pressing gently to ensure even coating.
12 - Serve immediately while warm for the best texture and flavor.
