This recipe came from Beatriz Cryns.

Serves 3.

Fry the onion slowly until soft and transparent (but not caramelised). Add the bacon and fry for another 5-10 minutes. Simultaneously, cook the spaghetti (as per the instructions on the packet).

Whisk together the egg yolks and cream. Once the spaghetti is cooked, drain it and return it to the same hot pan; stir in the onion and bacon, then stir in the cream and egg yolks; the heat of the other ingredients will cook the egg before serving. Mix thoroughly, and add pepper and salt to taste.
