Wait, the article says to use parmesan, eggs, pancetta and spaghetti? Uh, it is pecorino, eggs, guanciale and spaghetti. This is basically the only way to get the best results. You can fuck with any other italian pasta, but carbonara is only good if done exactly with these four ingredients. And of course a ton of black pepper.

I know, I tried every possible combination. The only one that makes sense is the one with pecorino and guanciale.
