4 egg yolks + 1 egg
1/2 cup grated Pecorino Roman cheese (I often use parmesan, cause that is what I usally have on hand)
5 1/2 oz of diced guanciale or a good quality smoky bacon (I always use bacon cause that is what I have on hand)
12 oz of spaghetti
2 tablespoons of extra virgin olive oil
Freshly ground black pepper
The first thing you will need to do is to boil you spaghetti in lightly salted water at a steady boil. Keep the salt low because both the meat and the cheese are already salty. Saute the meat in a thin layer of olive oil. Once the meat is golden and crispy, take it off the heat and leave it to cool for a few minutes.
In a bowl, put the 4 egg yolks plus 1 whole egg. Whisk them together until completely mixed. Add the cheese, mix it in well, add the pepper. If the sauce seems too dense. you can thin it by adding some of the water from the pasta a little bit at a time. Now add the cooled meat. Mix sauce ingredients together. Drain the pasta, leave a little moist--don't get rid of all the water. This will help to thin out the sauce so it coats all the pasta. Now, mix it together, and once the pasta is coated, serve it right away.
