Bring a pot water to the boil in readiness to cook the gnocchi.
For the gnocchi, place ricotta, parmesan, egg yolks, nutmeg and 2/3 of the flour. Add the salt and pepper.
Use your hands to mix to form a soft dough. Add the remaining flour if required. The dough should be very soft & it should only just hold together.
Transfer the dough to a floured surface and cut into 4 pieces. Roll each piece into a sausage shape approx. 1.5-2 cm in diameter. Dust the bench with a little flour or semolina, as required.
Cut each roll into 2 cm lengths. Handle gently as they will be fragile.
The pot temperature should be reduced so it is a gentle rolling boil.
Carefully lower about a third of the gnocchi pieces (a few at a time so you don’t knock too much of the water temp out). After 2-3 minutes, they will rise to the surface. Lift these out using a slotted spoon.
Gently transfer cooked gnocchi to the pan holding your sauce and then stir over a low heat until coated and warmed through. Divide among bowls and then serve with extra parmesan.
Fresh basil leaves or Italian parsley leaves, to serve – optional.
