In a large mixing bowl (a stand mixer is best if you have it) dissolve the yeast and sugar in warm water. 2 - .25 oz packages active dry yeast , 3 TBS granulated sugar, 2 1/2 cups warm water
Add the melted butter into the mixture and stir it in. 3 TBS unsalted butter
Add in 2 cups of flour to the yeast mixture, and the salt. Stir till combined. 6 1/2 cups all purpose white flour, 1 TBS salt
Add 1/2 cup of the flour at a time, while stirring slowly, combining thoroughly after each addition. Until you've added 6 cups of flour total.
Add more flour 1 TBS at a time as needed till the dough is pulls away from the sides of the bowl. (Mine needed 6 1/4 cups total)
After the dough pulls from the sides, knead it for 8 minutes.
Grease a bowl with oil. 1 TBS olive oil
Roll the dough into a ball and place it into the bowl. Brush top of the dough ball with oil too.
Cover with a towel or greased plastic wrap and set the bowl in a warm place, to let it rise.
Let the dough rise till doubled in size, about 1 hour.
Punch the dough down to remove the air.
Divide the dough into two equal halves.
Roll each loaf into a flat rectangle, about 9inches (as wide as the bread pan) and about 1/2 inch thick.
