Spaghetti al pesto Genovese

Start by preparing the dressing: take the fresh basil leaves and wipe them with a clean kitchen towel. Then place them inside a high-sided glass. Add the peeled garlic, pine nuts and grated cheese. Start blending, adding just enough olive oil to obtain a creamy, homogeneous and brightly colored sauce. Next, place a pot of water on the stove, bring to a boil and salt the water. Continue adding the spaghetti and cook for 7-9 minutes. When the pasta is cooked, drain it, keeping a small cup of pasta cooking water. Put the pesto in a large bowl, dilute it with a little of the cooking water, stir and add the spaghetti. Stir well to bind the pasta to the sauce, and finally, serve. Finish by garnishing with fresh basil and a sprinkling of cheese if necessary. Your Spaghetti with pesto is ready, enjoy!
