Broccoli and Grilled Corn Salad

Bring a large pot of water to a boil. Salt it lightly, add the broccoli and cook uncovered, stirring once or twice, until just crisp-tender, about 5 minutes. Drain, transfer to a bowl of iced water and, when cool, drain again and pat dry.

Light a charcoal fire and let it burn down to medium-hot or preheat a gas grill to medium-high. Position the rack about 6 inches above the heat source. Meanwhile, brush the ears of corn on all sides with 3 tablespoons of the oil. When the grill is ready, lay the corn on the rack. Cover and grill, turning occasionally, until the corn is lightly and evenly browned, about 12 minutes. Transfer to a cutting board and cool.

With a long, sharp knife, cut the kernels off the ears and transfer them to a bowl. Add the remaining 5 tablespoons oil, vinegar, sugar, celery seed, mustard, salt and pepper. Stir in the corn and the onion. The salad can be prepared to this point several hours in advance. Cover and refrigerate, returning it almost to room temperature before proceeding.

TO SERVE: Stir in the broccoli. Adjust the seasoning. Serve within 30 minutes or so of completion.
