Add the flour. If the mixture doesn't need all the flour, it's not needed. The consistency of the mixture should be hard enough to form gnocchi-like shapes with spoon, but not too hard as a dough.
Mix the ingredients well, than make some saltwater boil.
Form little dumplings from the batter and carefully place them into the boiling water.
Cook the dumplings until they come up to the surface of the water and not more.
