- In a large bowl, dissolve the yeast and sugar in warm water and let sit for 5 minutes until frothy.
Add flour, salt, rosemary, and parmesan cheese to the yeast mixture. Mix until a dough forms.
- Knead the dough on a floured surface for about 5-7 minutes until smooth and elastic.

- Preheat oven to 450°F (230°C) and line a baking sheet with parchment paper.
- Bring 10 cups of water to a boil and add the baking soda.
- Divide the dough into 12 equal pieces. Wrap each piece around a mozzarella stick and seal the ends.
- Drop each pretzel into the boiling water for 30 seconds, then remove with a slotted spatula and place on the baking sheet.
- Brush each pretzel with the beaten egg and sprinkle with coarse sea salt.
- Bake in the preheated oven for 12-15 minutes, or until golden brown.
