Ingredients

  • 12 large sea scallops
  • 3 tablespoons fresh lemon juice
  • 4 tablespoons extra virgin olive oil
  • Coarse (kosher) salt and freshly ground black pepper, to taste
  • 1 ruby grapefruit
  • 2 blood oranges, or 1 small navel orange
  • Vegetable oil, for the grill
  • 1 or 2 large bunches watercress, rinsed and patted dry, tough stems removed
  • 2 tablespoons chopped fresh flat-leaf parsley leaves, for garnish

Method

  • Preheat a barbecue grill to high.
  • While the grill is heating, place the scallops in a bowl and add the lemon juice, 2 tablespoons of the olive oil, and the salt and pepper.
  • Toss, and let rest for 20 minutes at room temperature.
  • While the scallops are marinating, cut the skin and the white pith off the grapefruit and oranges.
  • Using a small sharp knife, cut out the segments, holding the fruit over a bowl to catch the juices.
  • Place the segments in a second bowl.
  • Squeeze the membranes over the juice bowl to extract any extra juice.
  • Season the juice with salt and pepper to taste, and then whisk in the remaining 2 tablespoons olive oil.
  • Set both bowls aside.
  • Thread 3 scallops on each of four skewers, leaving a little space between them for even cooking.
  • Oil the grill grate well and arrange the skewers on the grate.
  • Grill until the scallops are just cooked through, 2 minutes per side.
  • Divide the watercress among four large salad plates.
  • Drizzle it lightly with the citrus dressing, and then arrange the grapefruit and orange segments on top.
  • Place 3 grilled scallops in the center of each plate.
  • Garnish with the parsley, and serve.
