Turn the dough out onto a lightly floured work surface (I just use my countertop). Knead the dough for about 10 minutes. Sprinkle more flour onto the work surface and your hands as needed, if the dough begins to stick. To see if you've kneaded enough, you can press two fingers gently into the dough. If the indentations stay after you move your fingers, then it's been kneaded enough and is ready for the next step.
