Method
- Toast peppercorns briefly, then crush coarsely.
- Cook pasta in less water than usual so the water gets very starchy.
- Mix Pecorino with a little warm pasta water into a thick paste.
- Transfer al dente pasta to a warm pan off heat with pepper and a splash of water.
- Fold in cheese paste gradually, adding water until glossy.
- Serve immediately with more pepper.
Cook's note: The cheese clumps if the pan is too hot. Build the sauce off heat.
