Step 1

Bring a large pot of water to a boil. Add 1 tablespoon salt.

Step 2

In a 4-quart saucepan, add 1 cup heavy cream, the butter and a pinch of salt and bring to a very light simmer over medium-low to low heat. Let reduce for about 15 minutes. Add the remaining 1/2 cup cream and season with salt and pepper.

Step 3

Meanwhile, cook the pasta until super al dente. Reserve some pasta water and drain the pasta. Add the pasta to the reduced cream, along with the cheese and nutmeg. Stir to combine and adjust the thickness with pasta water if necessary. (Keep in mind the sauce and pasta will tighten up as it cools and as you plate it.) Taste and adjust the seasoning with more salt if necessary. Garnish with more cheese.

Step 4

Serve instantly!
