In a medium bowl, combine warm water, active dry yeast, and granulated sugar. Let it sit for 5-10 minutes until frothy.

In a large mixing bowl, whisk together all-purpose flour and salt. Add the yeast mixture and melted butter, mixing until a rough dough forms.

Knead the dough on a floured surface for 5-7 minutes until smooth. Place in a greased bowl, cover, and let rise for 1 to 1.5 hours.

Once risen, punch down and divide into 8 portions. Roll each into an 18-inch rope and twist into a pretzel shape.

Preheat oven to 375°F. Boil 10 cups of water and stir in baking soda. Drop pretzels in batches for 30 seconds.

Remove boiled pretzels, brush with beaten egg, and sprinkle with cinnamon-sugar mixture.

Bake for 12-15 minutes until golden brown. Cool on a wire rack before serving.
