Prepare the Yeast: In a small bowl, dissolve the yeast and sugar in warm water. Let it sit until frothy.

Mix Ingredients: In a large bowl, combine the flour, salt, rosemary, and Parmesan. Pour in the yeast mixture and stir until a rough dough forms.

Knead the Dough: Turn the dough onto a floured surface and knead for 5-7 minutes until smooth and elastic.

First Rise: Shape dough into a ball, place in an oiled bowl, cover, and let it rise until doubled, about 1 hour.

Preheat Oven: Preheat oven to 450°F and line a baking sheet with parchment paper.

Boil the Pretzels: In a pot, bring water and baking soda to a boil. Boil each pretzel for 30 seconds.

Shape the Pretzels: Divide dough into 12 pieces, roll into ropes, and wrap around mozzarella sticks, sealing ends.

Boil & Bake: Boil each pretzel, transfer to baking sheet, brush with egg, sprinkle salt, and bake until golden brown.

Finish with Butter: Brush baked pretzels with melted butter and let cool slightly before serving.
