In a large bowl, combine flour, salt and sugar. Add water and yeast mixture. Mix until combined. It will be sticky.

Cover with plastic wrap that has been sprayed with cooking spray. Place in a warm draft free place until double, about 1 hour.

Spray 3 loaf pans with cooking spray and sprinkle with a hand full of cornmeal. Tilt the pans so they are coated with cornmeal.

Spray hands with cooking spray and punch down dough. Divide into three pieces and place in loaf pans. Cover with plastic wrap sprayed with cooking spray and place in warm draft free place for about 30 minutes until dough is slightly over the top of the pans.

While dough is rising, preheat oven to 350º. Cook for 30 minutes. Remove one at a time and brush with melted butter. Return to oven and cook for an additional 10 minutes until lightly golden brown.

Immediately turn the loaves onto a rack and brush again with melted butter.
