In a mixing bowl, combine warm water, active dry yeast, and granulated sugar. Allow to sit undisturbed for 5-10 minutes until frothy.

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

Transfer the dough to a floured surface and knead for about 5-7 minutes until smooth and elastic.

Place the kneaded dough into a lightly oiled bowl, cover with a towel, and let it rise in a warm area for 1 to 1.5 hours, or until doubled in size.

Once risen, punch the dough down, divide into 8 pieces, and roll each into an 18-inch rope, shaping into a pretzel.

Preheat the oven to 375°F (190°C).

In a pot, bring 10 cups of water to a boil and stir in baking soda. Boil each pretzel for 30 seconds, then transfer to a parchment-lined baking sheet.

Brush each pretzel with the beaten egg. Mix granulated sugar and ground cinnamon, then sprinkle over the pretzels.

Bake the pretzels for 12-15 minutes, until golden brown.

Let cool on a wire rack for a few minutes before serving.
