Goat cheese melts into the cream sauce to make it even creamier. The lemon juice brightens the sauce, and a glance of nutmeg adds a final note. Feel free to play around with this one! Swap out a different cheese, or experiment with different herbs like thyme or basil, or even add some heat with a few chili pepper flakes. Kosher salt and freshly ground black pepper Reserve a half cup of the cooking water for adding back to the pasta if needed. (Reserve the rest of the Parmesan to sprinkle on before serving.)
