Wash and dry duck thoroughly, inside and out. Either poke holes into the skin being careful not to pierce the meat or use a sharp knife to score the skin in a crisscross pattern. Season duck inside and outside with salt and pepper. Place onion, celery and carrot in the cavity.
Place on roasting pan that has a wire rack, breast side down.
Bake at 300°F for one hour. Carefully remove the duck from the oven and flip it over so that it is breast side up. Bake again for another hour and repeat the process two more times, so that it cooks for the last hour breast side up. The last 45 minutes or so, brush the skin with the cherry balsamic glaze.
Let rest for at least 30 minutes before cutting.
