Add about 2 Tbsp more flour, stirring to form a shaggy, drier dough. Turn out onto a lightly floured countertop. Knead the dough, adding just enough flour to keep it from sticking, until it is smooth and elastic. The more you knead, the less sticky it will become. Add ONLY enough flour to keep the dough from sticking to the counter, and use a light hand as you knead.
