Grilled Scallops with Flower Foam, Watercress Salad and Orange-Shallot Vinaigrette

Edible flowers (a mix of pansies, marigolds, snapdragons, chive flowers, and sage flowers) are used in two ways - in a foam to top these gorgeous grilled scallops and in a salad mixed with watercress and drizzled with orange and caramelized shallot vinaigrette.
