About this recipe: Unlike a lot of recipes out there for spaghetti carbonara, this is the true Italian recipe from an Italian! You can't get more authentic than this recipe! Note there's no cream, just eggs, and Pecorino Romano cheese is used, not Parmesan.
If the egg mixture becomes too thick, add a little of the cooking water from the pasta to dilute the sauce. But remember, the eggs should never be scrambled!
