Dissolve the yeast in the warm water and let it sit for 5 minutes, until foamy.

In a large bowl, combine the yeast mixture, sugar, salt, egg, melted butter and 1 cup of the flour. Mix well.

Stir in the remaining flour a little at a time until you have a soft dough. Knead on a lightly floured surface for about 5 minutes, until smooth and elastic.

Shape the dough into a ball, place it in a greased bowl and turn to coat. Cover with a towel and let it rise in a warm spot until doubled, about 1 hour.

Punch the dough down and divide it into 16 pieces. Roll each into a smooth ball and place on a greased baking sheet. Cover and let rise 20 to 30 minutes.

Bake at 350°F for 12 to 18 minutes, until golden brown. Brush with butter and serve warm.
