Creating Authentic Pasta Carbonara is a simple process. Follow these steps for the best results:

1. Boil Pasta: In a large pot, bring salted water to a boil. Add the spaghetti or fettuccine and cook according to package instructions until al dente.
2. Cook Pancetta: In a frying pan over medium heat, cook the diced pancetta or guanciale until crispy, about 5-7 minutes. Remove from heat.
3. Prepare Sauce: In a bowl, whisk together the eggs, grated Pecorino Romano cheese, and a generous amount of black pepper. Set aside.
4. Combine Pasta and Pancetta: Once the pasta is cooked, reserve a cup of pasta water, then drain the pasta. Quickly add the hot pasta to the pan with pancetta. Toss to combine.
5. Add Sauce: Remove the pan from heat. Pour the egg and cheese mixture over the hot pasta, stirring quickly to create a creamy sauce. If too thick, add reserved pasta water a little at a time until desired consistency is reached.
6. Serve Immediately: Plate the Carbonara and top with additional Pecorino Romano cheese and freshly cracked black pepper.

Following these steps will lead you to a deliciously rich and creamy dish that captures the essence of Italian cuisine.
