Cacio e Pepe

Here are the simple ingredients, and directions:
1/2 box Pasta (pappardelle or tagliatelle is best, it provides a wide surface for the cheese)
1 Cup finely grated Pecorino Romano cheese
2 or 3 coarsely ground peppercorns
Directions:
In a large pot of salted water, bring the water to a boil and cook the pasta. A few minutes before the pasta is ready, heat a medium-sized saucepan and toast the pepper for a few minutes. Add 1/2 cup of pasta water to the pan, then add the pasta and mix. Gradually add the cheese, 1/4 cup at a time, and mix between each addition. That's it! Serve immediately while the cheese is hot and creamy.
