Step 1: Combine warm water and 1 tablespoon of sugar in a bowl. Sprinkle the yeast on top and let it sit for 5-10 minutes until foamy.
Step 2: Add the flour, salt, and 2 tablespoons of melted butter to the yeast mixture. Mix until a dough forms.
Step 3: Knead the dough for about 5 minutes until smooth and elastic. Place in a greased bowl, cover, and let rise for 1 hour.
Step 4: Preheat your oven to 450°F (230°C) and line two baking sheets with parchment paper.
Step 5: Bring 10 cups of water and the baking soda to a rolling boil in a large pot.
Step 6: Divide the risen dough into 12 equal pieces. Roll each piece into a 22-inch rope and twist into a pretzel shape.
Step 7: Drop each pretzel into the boiling baking soda water for 30 seconds, then remove with a slotted spoon and place on the baking sheets.
Step 8: Bake for 8-12 minutes until golden brown.
Step 9: In a small bowl, mix the 1/2 cup sugar and cinnamon. Brush the warm pretzels with melted butter and coat thoroughly in the cinnamon-sugar mixture.
