Step 1

Cook the spaghetti in a saucepan of boiling salted water according to the packet instructions. About halfway through cooking, scoop out a mugful of the cooking water from the pan.

Step 2

Meanwhile, in a large bowl combine the cheese and pepper. Gradually incorporate 2–3 tablespoons of the pasta water to create a thick paste. Using the back of a dessertspoon, spread the mixture evenly up the sides of the bowl.

Step 3

Drain the pasta and leave it to rest for 1 minute, then transfer it to the bowl, quickly swirling the pasta around so that the cheese melts and coats the strands, adding little drizzles of the starchy cooking water as you go to create a glossy sauce. Serve immediately.
