Sjemac, what time is dinner served? I'll bring the beer.
As for Rob's duck, unless you know what it was, where it came from, and what happened to it after it was shot, the reasons for the muddy taste are numerous.
I have had beautiful northern mallards that had been feeding in areas where salmon had spawned out and died, and I still gag when I think about it. Any of the ducks that eat a lot of aquatic insects (shovelers, blue wing teals, etc.) will usually be pretty strong. If you do decide to go hunting for ducks, try and find them either feeding in grain or legume (pea, bean) fields, or returning from them in the morning. These ducks are usually awesome. The best duck I have ever eaten are widgeons that had been feeding in grain fields, they were so fat! Absolutely mouth watering, finger licking, heavenly good. Sjemac has the idea though, do not overcook; same with deer meat, you already killed it once, you do not have to cook it to death as well.
Cheers
Ian
