01 - Combine warm water, yeast, and 1 tablespoon sugar in a large bowl. Let stand for 5 minutes until mixture becomes 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 use a stand mixer with dough hook for 5-7 minutes until dough is smooth, elastic, and passes the windowpane test.
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 volume.
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 steady boil.
07 - Turn dough onto lightly floured surface and divide into 8 equal portions. Roll each piece into a 20-inch rope, form a U-shape, cross ends over twice, and press tips to the bottom curve to create classic pretzel shape.
08 - Carefully lower each pretzel into boiling baking soda bath using a slotted spatula. Boil for 30 seconds per side, then transfer to prepared baking sheets.
09 - Bake pretzels for 12-15 minutes until deep golden brown with a glossy, crackled surface. Rotate pans halfway through for even browning.
10 - Immediately brush hot pretzels generously with melted butter while still warm to ensure coating adheres properly.
11 - Whisk granulated sugar and ground cinnamon in a shallow bowl. Roll each buttered pretzel in mixture until thoroughly coated on all sides.
12 - Serve pretzels immediately while warm for optimal texture and flavor. Best enjoyed fresh but can be refreshed in a 350°F oven for 3-4 minutes if storing.
