1/4 pound (100 g) guanciale (cured pig’s jowl), pancetta or bacon
1/2 cup (25 g) grated Pecorino Romano
4 egg yolks and 2 egg whites
1/4 cup (60 ml) heavy cream
salt and pepper to taste
400 grams spaghetti
1. Set pasta water to boil.
2. Meanwhile, dice the meat or cut into thin strips, sauté it in a tablespoon of oil till it’s well cooked, and drain the pieces on a paper towel. As soon as the water boils, salt it and add the pasta.
3. While the pasta’s cooking, lightly beat the yolks and one or two whites (just one white if you’re using the cream). As soon as the yolks and whites are combined, beat in the cheese, pinches of salt and pepper, and the cream, if you’re using it.
4. When the pasta’s done, drain it and transfer it immediately to a heated bowl. Add the pancetta and pour the egg mixture over the pasta, stirring briskly (the heat of the pasta will cook the eggs). Serve immediately.
