Bake potatoes until soft. Once cool, peel.
Pulverize in a food processor. Once smooth, add egg and salt.
Add 1 ½ c flour and process to combine. If your food processor can handle it, add another ¼ c flour.
Turn dough out onto well-floured surface. Kneed about 10 times until dough it smooth, adding more flour if still very sticky.
Cut dough into 4 segments. Work one piece at a time, covering remaining pieces with a towel or plastic wrap so they don’t dry out. Roll into a thin log and cut into tsp size segments.
If desired, pieces can be processed further – rolling against a fork or grooved board to create ridges.
Use immediately or freeze separately on a baking sheet before storing in a plastic freezer bag.
To cook, heat a medium pot of water to boiling. Add 1 tsp salt and desired amount of gnocchi. Stir gently a couple times to ensure they do not stick to the bottom. Cook until gnocchi float to the surface. Drain.
