Tagliolini with Arugula-Walnut Sauce
I LOOOOOVE nuts. And this super-classic preparation, which is hugely flavorful and really easy to make, is all about them. I start by toasting and puréeing walnuts—both of which help bring out their flavor and natural fattiness. Combine them with some sharp cheese and spicy arugula, and you end up with a dish that’s luscious and palate cleansing at the same time.
