Broccoli and other cruciferous vegetables, like cabbage and brussels sprouts, can handle some char. Blackening makes them sweet and caramelized rather than bitter and burnt. The key is to cook the vegetables hot and fast, so the pieces develop color without becoming mushy and they’re crackly at the edges while still crisp-tender at the cores. Make sure your broccoli florets are thoroughly dried before cooking by taking them for a ride in a salad spinner. (Water will slow down the browning, resulting in florets that steam instead of char.) A topping of toasted nuts, sticky dates, bright lemon and bites of peppercorn adds complexity to this humble vegetable.
