GRILLED DUCK BREAST WITH MISO, GINGER AND ORANGE

Steps:

• Trim duck breasts of extraneous fat (or ask your butcher to trim them) and score the skin. Season very lightly with salt and generously with coarsely ground pepper.
• Make the marinade: In a mixing bowl, whisk together miso, soy sauce, sake, orange zest, ginger, garlic, cayenne and sesame oil. Remove 1/4 cup of the marinade and combine it with 2 tablespoons orange juice to make a dressing; set aside. Add remaining 2 tablespoons orange juice to the marinade in the mixing bowl.
• Lay duck in a shallow pan and pour the marinade over, making sure meat is well coated. Let sit at room temperature for at least 1 hour. If you wish, cover and refrigerate for up to 1 day; bring to room temperature before proceeding.
• Prepare a bed of medium-hot coals in a grill, or heat a stovetop grill or cast-iron pan to medium hot. Cook duck breasts skin-side down for 8 to 10 minutes, until fat is rendered and skin is nicely colored. (See note.) Turn and cook on the other side for 3 or 4 minutes, until internal temperature registers 125 degrees. Remove from heat and let rest at least 10 minutes.
• Meanwhile, bring a pot of well-salted water to a boil. Cook green beans for 1 to 2 minutes, until firm-tender. Drain green beans and rinse with cool water; blot dry.
• Slice duck crosswise about 1/8-inch thick. Line a platter with lettuce leaves. Place several slices of duck on each leaf, along with a couple of mango slices. Arrange green beans over the top and garnish with watercress, if using. Drizzle reserved dressing over everything, sprinkle with scallions and serve.
