“Since traditional pesto genovese consists of nothing more than basil, garlic, nuts, olive oil, salt, and cheese, the quality and variety of the ingredients you choose really matter. When it comes to basil, shop for the youngest herbs you can find, with the smallest, palest leaves. The smell should be aromatic, not licorice-like. If you can’t find young basil, soften the bitterness of deep green mature leaves by blanching them in almost boiling water for 30 seconds, then plunge them in an ice bath.”
