Grilled Stuffed Duckling

Step 1
Bring water to a boil in a saucepan; remove from heat and stir couscous into the water. Cover saucepan and let stand until water is absorbed completely, about 10 minutes. Fluff couscous with a fork.

Step 2
Heat 1 1/2 tablespoons butter in a skillet over medium heat. Add onion, mushrooms, and serrano peppers; cook and stir until lightly browned, about 5 minutes. Mix in the cooked couscous and cayenne pepper.

Step 3
Fill the duckling's cavity with the couscous mixture. Spread 1 tablespoon butter in a thin layer over the duckling's skin. Rub skin with basil, salt, and pepper. Wrap in aluminum foil.

Step 4
Preheat grill for medium heat, about 300 degrees F (150 degrees C). Lightly oil the grate.

Step 5
Place duckling on grill and cook for about 30 minutes, turning once. Remove foil; continue grilling, turning occasionally and basting with butter each time. Cook until no longer pink at the bone and the juices run clear, 25 to 30 minutes. An instant-read thermometer inserted into the thickest part of the thigh, near the bone should read 180 degrees F (82 degrees C).

Step 6
Remove the duckling from the grill, cover with a doubled sheet of aluminum foil, and allow to rest in a warm area for 10 minutes before slicing. Spoon out the couscous and serve alongside the duckling.
