For the spaghetti carbonara, cook the pasta al dente and set aside. Dice the ham. Heat oil in a pan and fry ham in it.
Whisk yolks with whipping cream and Parmesan cheese, season with salt and pepper.
On the turned off but still heated stove top, quickly mix the sauce with the still hot pasta and ham until the yolk binds.
Season the spaghetti carbonara with salt, pepper and nutmeg.
