Bring the cream and butter to a boil in a saucepan large enough to hold the cooked fettuccine.
Reduce the flame to low and add the salt, pepper, and nutmeg.
Add the cooked fettuccine and toss in the sauce.
Add the Parmesan cheese and toss until the fettuccine are well coated and the sauce has thickened.
