Grate your own cheese – pre-shredded bags contain anti-caking agents that prevent smooth melting. Keep the heat low once the cheese is added; if the sauce bubbles aggressively, the cheese can separate. Salt the pasta water generously – it is your only chance to season the pasta itself. If the sauce seems too thick after adding the pasta, use the reserved starchy water to loosen it without thinning the flavor.
