n Napa Valley, where I live, it is too hot to cook much this week. Triple-digit days almost (almost) take my appetite away. Riffling through my mental inventory of pasta sauces that don’t require cooking, I remembered a wonderful one that my husband and I enjoyed years ago in Lipari, one of the Aeolian islands. I have made this pesto—a blend of tomato, almonds, capers, basil and mint—many times since.

Pecorino romano is the cheese you want here. I don’t think Parmigiano-Reggiano would taste right at all. Save any leftover pesto to spread on bruschetta.
