Wash and dry hands and remove ball to cutting board. Knead the dough, occasionally dusting with 1 teaspoon flour, until a firm, smooth homogenous ball is formed, about 15 minutes. Place ball of dough in a lightly oiled mixing bowl, cover with a clean kitchen towel and allow to rise in a warm place until its size is doubled, about 2 hours. Punch down and divide into 4 pieces. Dough is now ready for use.
