Saute onions (1 large, chopped) to tender in butter (1-2 T), add sliced apples (3-4,
not soft ones like delicious), throw in diced duck and legs if desired (hey, don't waste those legs

), cook almost through, stir in flour (1 T for each cup of broth used) and curry powder (1-2 T or to your taste) and a little chile powder if desired, slowly stir in chicken broth (about 2 C, I like lots of sauce), simmer until thickened,. serve over rice.
I did this recipe with just legs (your buddies will usually gladly let you have all their duck legs though you might have to remove them from the carcasses yourself

) for a potluck and they were a hit, kind of like chicken wings. For the legs I put them in a slow cooker, just covered with water, and cooked for about three or four hours, nice and tender! Follow recipe as above.
I usually serve this with chutney as the spice warm dish combines with tangy cold chutney very well. If chutney is too expensive you can mix mincemeat (the raisiny stuff) with some peach jam, vinegar, garlic and onion powder and brown sugar. I don't really have a recipe for this.
Enjoy!
