Spaghetti alla Carbonara

Ingredients

• •450 g (1 pound ) spaghetti
• •225–500 g (½–1 pound) guanciale or pancetta
• •5 egg yolks
• •178 ml (¾ cup ) grated Pecorino Romano cheese
• •178 ml (¾ cup) grated Parmigiano-Reggiano cheese
• •3–4 tablespoons extra-virgin olive oil
• •½ tablespoon freshly-ground pepper
• •Salt

Instructions

1. 1Dice the guanciale or pancetta into 2.5 cm (1- inch ) pieces.
2. 2Bring a big pot of water to a boil and add salt to taste when it begins to simmer .
3. 3Cook the spaghetti until it is al dente and drain it, reserving 1 cup of water.
4. 4While spaghetti is cooking, heat the olive oil in a large skillet over a medium-high heat. When the oil is hot, add the pancetta and cook for about 10 minutes over a low flame until the pancetta has rendered most of its fat but is still chewy and barely browned.
5. 5In a bowl, slowly whisk about ½ cup of the pasta water into the egg yolks. Add the grated cheese and mix thoroughly with a fork.
6. 6Strain the spaghetti and transfer it immediately to the skillet with the pancetta. Toss it and turn off the heat.
7. 7Add the egg and cheese mixture to the pasta while stirring in the remaining pasta water to help thin the sauce and create an emulsion.
8. 8Add the pepper and toss all the ingredients to coat the pasta.
