I made duck a la Moonbear tonight. When I thawed the duck, I was planning on duck a l'orange, but never got around to getting any of the ingredients, so improvised with what I had. Roasted the duck with basic poultry seasonings while making a sauce for it. (Turbo, close your eyes so you don't cringe too much.) I only had beef broth from the store and no bones or stock, so it ended up a bit too salty making a reduction sauce with that. It came out well enough, I'll do the recipe again with homemade stock next time. (Okay, you can open your eyes again.)
So, I started out sauteeing garlic and onions in oil...started with a hot pan to slightly brown the garlic, then reduced the heat to let them clear. I added the zest of one lemon, let it saute a bit longer, then added juice fom half the lemon (the other half I cut into slices and put on the duck while roasting, though I don't think it did anything much). Then I added half the broth and some celery along with everything from the duck that wasn't getting roasted...the organs, neck, tail that was still attached and I snipped off and some extra skin that would only be needed if you wanted to stuff and close the cavity. I added some black pepper and a bay leaf at that point, and I let that simmer and reduce about an hour, then added the remaining broth and let it reduce another 45 min. I basically went from 4c liquid to 1c liquid. I strained that and set aside. I then melted about a tablespoon of butter and added a generous splash of triple sec (because I still wanted at least a hint of orange) and a more generous couple of splashes of dry sherry and let that reduce down a bit, and added about a half tablespoon of flour and stirred over medium low heat for a while until everything started caramelizing to a dark brown (it wasn't enough flour to thicken the sauce, but the caramelization for flavor is what I was aiming for, though it did have a texture similar to a roux). I added a little of the actual pan drippings, since the duck was nearing the end of roasting by then, and then whisked the reduction back in and brought it to a slow boil just to thicken very slightly...I didn't want gravy, but was aiming for a sauce just thick enough to cling to the duck when poured over it. After the duck rested out of the oven, I cut off the breasts, removed the skin (because I haven't mastered crispy duck skin no matter how brown it gets) and sliced into thick slices against the grain, put some on a plate and poured a couple spoonfuls of sauce over it. Yummy! It was even better than I expected considering the broth I used and that I was just randomly adding ingredients as I went.
