In a small bowl, combine 1 packet of active dry yeast with 1 cup of warm water and 2 tablespoons of granulated sugar. Stir gently and let this mixture rest for 5-10 minutes until it becomes foamy.

In a large mixing bowl, whisk together 4 cups of all-purpose flour and 1 teaspoon of salt. Pour in the yeast mixture and ¼ cup of melted unsalted butter. Mix until a shaggy dough forms.

Turn the dough onto a floured surface and knead for 5-7 minutes until smooth and elastic. Place the dough in a lightly greased bowl, cover, and let it rise in a warm spot for 1-1.5 hours.

Once risen, punch down the dough gently and divide it into 8 equal pieces. Roll each piece into a long rope, twist into pretzel shapes, and press to seal.

Preheat your oven to 375°F (190°C). In a large pot, bring 10 cups of water and ⅔ cup of baking soda to a rolling boil. Boil each pretzel for 30 seconds.

Remove the boiled pretzels from the pot and place them on a parchment-lined baking sheet. Brush with beaten egg and sprinkle with a mixture of ½ cup of granulated sugar and 2 teaspoons of ground cinnamon.

Bake for 12-15 minutes or until golden brown. Allow to cool slightly before serving.
