Add a good pinch of salt to the pot of boiling water and cook the pasta until al dente. Add the pasta straight to the pan and toss well. Add a ladle of the pasta water to the pan before adding the egg yolks one at a time, stirring through after each one. Add the parmesan cheese and a good helping of cracked black pepper, tossing through. If the pasta seems a little gluggy, add some more pasta water until glossy.
