Ingredients
About 4 tablespoons good quality EVOO – Extra Virgin Olive Oil
1/2 pound (2 slab-cut chunks) meaty pancetta or guanciale, cut into small dice
4 large cloves garlic, chopped
About 1 teaspoon coarsely ground black pepper
1 cup white wine
6 large egg yolks
Salt
1 pound pasta, such as chitarra (guitar string spaghetti), square-cut spaghetti or linguini
1 cup grated Pecorino Romano, plus more to pass
1 cup grated Parmigiano-Reggiano, plus more to pass
1/2 cup flat-leaf parsley, finely chopped
Directions
Bring a large pot of water to a boil for pasta.
In a large, deep skillet over medium heat, heat olive oil, 4 turns of the pan. Add pancetta or guanciale and brown 3-4 minutes. Add garlic and black pepper, and stir 1-2 minutes more. Add wine and reduce by half then reduce heat of pan to low.
In a bowl, whisk up egg yolks and season with salt. Add both grated cheeses to egg yolks while whisking.
Add pasta to liberally salted boiling water and cook to 1 minute less than al dente per package recommendation.
Remove 1 full cup of starchy cooking water and whisk into egg yolks in a steady stream to temper them. Reserve an extra half-cup of starchy water in case the pasta gets too tight when you toss it.
Drain pasta and add to the pan with the pancetta and garlic. Remove from heat and toss with tempered egg yolks and handfuls of parsley. Adjust salt and pepper to taste.
