Cook the pasta according to the basic recipe. In the meantime, wash the lemon with hot water and rub the peel. Squeeze out the juice and pour it through a sieve into a bowl.
Peel the garlic and press it into the bowl, season with salt and pepper. Beat vigorously with a whisk, slowly pouring in the olive oil. Stir in the lemon zest and parsley.
Drain the pasta, drain briefly and mix quickly with the sauce. Serve sprinkled with the cheese.
A Frascati Superiore is recommended for this; I think a Pino Grigio also fits perfectly.
