In bowl of an electric mixer; mix together yeast and warm water. Add 1 Tbls sugar, and let stand for 5 minutes until foamy.
Add 1/2 cup sugar, milk, eggs, salt and butter. Slowly add enough flour to form a stiff ball. Turn onto a floured surface and knead for 6 to 8 minutes. Add additional flour if needed. Dough will be smooth and elastic when done.
Place dough in a well oiled bowl, turning to coat. Cover and let rise for about 90 minutes, or until doubled in size.
Punch down the dough, and divide into 3 equal parts. Roll each part into a 12 inch circle. Using a sharp knife cut each circle into 8 wedges.
Roll up the wedges, starting with the wide end going towards the point. Place on a lined baking sheet with the pointed end down. Cover and let rise for 30 minutes.
Preheat oven to 375 degrees.
Bake for 10-12 minutes until golden brown. Remove from oven and brush with melted butter if desired.
