Without delay, divide the dough into 6 pieces. On a floured work surface, roll each piece into a long ½-inch (1 cm) thick rope. With a knife, cut each rope into ½-inch (1 cm) gnocchi. Lightly dust with flour. If desired, roll the gnocchi over a gnocchi board or with a fork until rounded and grooved. Set aside on a lightly floured baking sheet. The gnocchi can be frozen at this stage, if desired.
