The secret to the success of this broccoli salad is that it handles the florets and stems differently. The florets are blanched briefly, just long enough to soften them and make them juicy, while still preserving their crisp, fresh bite. The stems, meanwhile, are left raw, for a refreshing crunch. Tossed with radicchio and a bold vinaigrette made from basil and pistachios, this is a salad to make you love all the parts of broccoli.
