I'm a fan of Master Foods Thai Seasoning. I use the stuff on chicken and fish, I will sprinkle it all over the meat and wrap it in foil with a piece of lime, then bake in over. Lemon works just as well and i have used orange with duck done the same way, Another one for duck (could use chicken) is cover bird with mustard leave in fridge 6-8 hours to let mustard soak in to skin, cut up some apples remove skin and core, stuff them inside bird then use a skewer to hold them in, I prefer to tie the bird (stops it falling appart when cooking) then rub honey all over it. Then stick it in the oven, 180C 45-60 min, a cup of white wine goes good in the bottom of the tray.
Hope this helps
