Heat cream in a medium saucepan over medium heat until simmering.
Reduce heat to low and add parmesan cheese, stirring frequently.
Continue to simmer and stir until the cheese is totally melted and the sauce has reduced slightly, about 5 minutes.
Add nutmeg and stir to combine.
Serve over your favorite pasta topped with fresh parsley.
Use the highest quality cheese you can, it will melt much better and stay combined with the sauce. I usually use this amount of sauce for 1 to 1 1/2 pounds of pasta.If the sauce becomes thick, add a splash of cream or half-and-half, or even milk to thin it out a little bit.When reheating the sauce, do so over low heat in a saucepan.If re-heating pasta with this sauce on it, microwave until the chill has just been taken off, add a splash of cream, stir, and microwave until warmed through.
