Don't forget Crepe Suzettes, Duck a la orange, marmalade, orange segments in a salad, orange sorbet, use slices inside of a whole fish, baste a chicken with the juice, make orange glace slices, fruit salad, glaze a ham with orange juice and stud with cloves (and don't forget to decorate with orange slices!), instead of lemon butter - use oranges, use it as the acid in your favourite salad dressing, cut in half and sprinkle sugar on top for a refreshing breakfast starter, look out a liqueur recipe (and make your own version of Cointreau!!) and the list goes on!!!
Too many restaurants, not enough time...
