Pasta carbonara has no cream in it. The creamy sauce is actually an emulsion made with beaten raw eggs and grated Pecorino. Spaghetti is the noodle most commonly used but fettuccine, rigatoni, linguine, or bucatini may be substituted.
Cook the pasta in about two liters of boiling water with the teaspoon of salt.
While the pasta cooks, fry the pancetta in a non-stick pan, allowing fat to be rendered.
While the pancetta browns and the pasta cooks, beat the eggs and grate the Pecorino.
When the pancetta is nicely browned, scoop out then pour off the fat leaving only a tablespoonful or so.
Drain the pasta (reserve a quarter cup of the pasta water) and immediately toss in the bacon fat. Turn off the heat.
Pour the beaten eggs over the Pecorino and whisk.
Season the egg-Pecorino sauce with pepper then add the pasta.
Toss the pasta with the sauce. If too thick, add the reserved pasta water, a tablespoon or two at a time, until the sauce is creamy but not too sticky.
Divide the pasta carbonara among three plates or bowls, sprinkle the bacon over the noodles and top with more grated Pecorino.
