This recipe guides you in creating a classic homemade pesto. It combines fresh basil, garlic, Parmigiano-Reggiano, and olive oil, with optional pine nuts and a touch of lemon, for a versatile, flavorful sauce perfect for pasta, sandwiches, or as a vibrant accompaniment to various dishes.
For vibrant green pesto, blanch basil leaves briefly in boiling water then shock in ice water before processing. Always use high-quality extra virgin olive oil and freshly grated Parmigiano-Reggiano for superior flavor. To prevent oxidation and maintain color during storage, cover the surface of the pesto with a thin layer of olive oil. Toasting pine nuts (if using) enhances their nutty aroma. Adjust garlic and lemon juice to taste – a squeeze of lemon brightens the sauce and helps stabilize color. Control the texture; some prefer a rustic, chunky pesto, while others like it smoother. Be mindful not to over-process, which can heat the oil and lead to bitterness.
