Cook your pasta in a pot of well salted water according to packet instructions. I tend to undercook dried pasta by a minute so it can finish cooking in the sauce. Reserve a cup of the pasta water before draining.
Melt the butter in a large skillet over a medium heat and add the pepper.
Let it sizzle together for a minute.
Add ¾ cup pasta water and whisk vigorously to emulsify. It will bubble up a lot. I like to shake the pan with my left hand and whisk with my right to really agitate it well. A flat whisk is brilliant here.
On a medium or medium low heat let it bubble gently for a minute to thicken slightly.
Add your cooked pasta and give it a toss in the sauce. Arrange the pasta in a nice even layer.
Lower the heat to the lowest possible and sprinkle the cheese directly onto the pasta in an even layer.
Let it melt gently on top for 1 - 2 minutes undisturbed (it doesn't have to be fully melted).
With tongs, spin the pasta around and around for 30 seconds or until a silky sauce emerges.
Serve immediately!
