Step 1: Prepare the Dough

1. In a large bowl, whisk together flour, yeast, sugar, and salt.
2. Add warm water and melted butter, mixing until a soft dough forms.
3. Knead on a floured surface for 5-7 minutes, until smooth and elastic.
4. Place dough in a greased bowl, cover, and let rise for 1 hour or until doubled in size.

Step 2: Shape & Stuff the Pretzels

1. Preheat oven to 425°F (220°C).
2. Punch down the dough and divide into 8 equal pieces.
3. Roll each piece into a 10-inch rope, then flatten slightly.
4. Place a mozzarella stick along the center and fold the dough over, pinching edges to seal.
5. Shape into a pretzel twist or leave as a cheese-stuffed breadstick.

Step 3: Give the Pretzels a Baking Soda Bath

1. In a large pot, bring 4 cups of water to a boil.
2. Add baking soda and stir.
3. Drop each pretzel into the bath for 20-30 seconds, then place on a parchment-lined baking sheet.

Step 4: Bake the Pretzels

1. Brush pretzels with egg wash and sprinkle with coarse salt.
2. Bake for 12-15 minutes, until golden brown.

Step 5: Add the Finishing Touches & Serve

1. Brush warm pretzels with melted butter for extra flavor.
2. Serve hot with marinara sauce, garlic butter, or honey mustard.
