In a small bowl, dissolve the sugar in warm water, then sprinkle the yeast over the top. Let it sit for about 5-10 minutes until it becomes frothy.

In a large mixing bowl, combine flour and salt. Create a well in the center and add the melted butter, egg, and activated yeast mixture.

Mix until the dough begins to come together. Transfer the dough onto a floured surface and knead for about 5-7 minutes until it's smooth and elastic.

Place the kneaded dough into a greased bowl, cover it with a clean cloth, and let it rise in a warm place for 30-45 minutes until it doubles in size.

After rising, punch down the dough and divide it into 12 equal pieces. Shape each piece into a ball and place them in a greased 9x13 baking dish.

Cover the rolls with a cloth and let them rise for another 30 minutes until they puff up.

During the second rise, preheat your oven to 375°F (190°C).

Bake for 20-25 minutes or until the tops are golden brown.

Allow the rolls to cool slightly before serving them warm with your favorite butter.
