Start by boiling a large pot of water and adding salt to season the pasta. This step is crucial to ensure the pasta absorbs the flavors throughout.

Add the spaghetti to the boiling salted water, cooking it for slightly less time than the package instructions suggest. Remember, the pasta will continue to cook in the sauce later on, so you want to keep it slightly al dente.

While the pasta is cooking, take whole black peppercorns and grind them to create freshly ground black pepper. This fresh pepper will add a burst of flavor to the dish.

In a separate skillet, toast the black pepper gently. This toasting process enhances the pepper's fragrance and complexity.

Now, it's time to create the creamy sauce. Add a small amount of hot pasta water to the skillet with the toasted pepper. The starch from the pasta water will help thicken the sauce and ensure it coats the pasta evenly.

Mix the sauce thoroughly, allowing it to simmer for a minute or two until it reaches a velvety consistency.

Once the spaghetti is cooked to perfection, drain it and transfer it to the skillet with the sauce.

Toss the pasta gently in the sauce, making sure every strand is coated with the rich and creamy mixture.

Serve immediately, garnishing with an extra sprinkle of grated pecorino Romano cheese and freshly ground black pepper for an extra touch of flavor.
