This is a cream-and-butter sauce finished with Parmigiano-Reggiano, pepper, and a tiny touch of nutmeg. The sauce comes together during tossing, so the pasta and pan heat do most of the work.
This sauce relies on the heat of freshly cooked pasta to melt raw grated cheese and butter into a smooth coating. Add them in stages and toss quickly so the cheese clings and the butter disappears into the strands.
