In a heavy bottomed saucepan melt the butter over medium-high heat.

Add the cream and bring to a boil. Immediately lower the heat to a simmer stirring constantly.

Cook for 7 minutes until the sauce begins to thicken.

Remove the saucepan from the heat and add the grated Parmesan cheese, dash of nutmeg and black or white pepper to your taste. Stir until the cheese is completely melted.

Serve immediately tossed with the cooked fettuccine and a sprinkle of freshly grated Parmesan cheese.
