In a large bowl, combine warm water, sugar, and yeast. Let sit for 5 minutes until frothy. Add flour, salt, and melted butter, then mix until a dough forms. Knead for 5-7 minutes until smooth and elastic.

Cover the dough with a damp cloth and let it rise in a warm place for about 1 hour, or until it doubles in size.

Preheat your oven to 425°F (220°C). Punch down the dough and divide it into 8 equal portions. Roll each portion into a 12-inch rope. Place a small amount of shredded mozzarella in the center of each rope and fold the dough over to enclose the cheese. Shape each piece into a pretzel.
