Cook the pasta according to the package directions.

Once you drain the pasta Prince with cold water until the pasta is cold, drain water so the pasta isn't wet.

In a tall container with an immersion blender place egg yolk, lemon juice, oil, and salt and blend until thick and creamy. You can use a food processor a small one with work best with this small-batch, drizzle in the oil as the remaining ingredients blend smooth.

Add more lemon if desired. I like it lemony and always add more lemon, just before serving.

Toss the pasta with sauce, add sliced basil leaves and top the pasta with grated cheese.

Add more salt if needed and add some black pepper.

Chill the pasta salad for at least an hour for the flavors to develop.

It's great served cold, at room temperature or heated.
