Cut the dough into four equal segments. Lightly flour work surface to prevent sticking. Take one segment of the dough, and roll into a ball.
Set it on the work surface, and roll into a rope 3/4-inch thick.
Use a sharp knife to cut 1-inch segments. Use a fork, tines facing down, to make the ridges. Hold one of the gnocchi and gently roll it from the bend in the fork, along the tines, pressing lightly. Repeat with remaining dough.
To cook gnocchi, heat a pot of salted water until boiling. Prepare an ice bath by setting up a bowl of water with ice cubes in it. Working in batches, add gnocchi to boiling water. Cook for a few minutes until gnocchi float to surface.
Remove gnocchi out of the pot with a slotted spoon, and dunk into ice bath to stop the cooking. Transfer gnocchi to a bowl, and lightly coat with
