1 ½cupsParmesanfreshly grated from a block or wedge
Instructions
Melt the butter over medium heat.
Add the cream and let it warm through gently. No boiling. We’re coaxing, not summoning a storm.
Take the pan off the heat.
Add the Parmesan a handful at a time, whisking like you mean it. Let each addition melt before adding more. The residual heat will melt it into a smooth, glossy sauce instead of a grainy mess.
If it feels a little thick, loosen it with a splash of hot pasta water. That starch pulls everything together like a good family secret.
Toss immediately with hot pasta and serve.
Notes
Storage:Best when served fresh but you can store it in an airtight glass container in the fridge for a day or two. Add a little milk if it thickens up too much.Tips:If it ever looks like it’s thinking about clumping or boiling, it’s too hot. Pull it off the heat faster than you’d pull gossip out of a church pew.
