Mix the cheese and pepper in a large bowl and set aside.
Add the salt to a large pot of water and bring to a boil.
Add the pasta, cook until al dente—about 13-15 minutes, and then turn off the heat.
Add a ladle of the cooking liquid to the cheese and pepper and whisk rapidly and strongly to make a smooth sauce, adding more of the pasta liquid one tablespoon at a time, if necessary.
Use a strainer to transfer the pasta to the sauce and tongs to coat all the strands.
