On a lightly floured board, knead the dough, adding a small amount of flour when necessary to keep from sticking. Knead for about 5 minutes. Place dough in a large, greased bowl. cover with a damp cloth and let sit in warm place for about 1 1/2 hours.
Grease a baking sheet with the remaining tablespoon of butter. Punch down the dough and knead it again for a few minutes. Shape the dough into a round, and place it on the greased sheet. Preheat the oven to 325*F.
