I had an open river blind up north of the Stag Island group for a couple of years

Out of the 200 plus ducks I killed killed out of it-- only 1 greenhead so that meant I had plenty of bluebills and goldeneyes to experiment on.

I can attest that there is not enough milk, buttermilk, tomato sauce, vinegar, marinades both common and secret ingredient types, stroganoffs, chowders and even bacon that can make those crustacean, fish and other assorted aquatic items eating POS anywhere close to being palatable....

much less even come close to a teal, pintail, gadwall, mallard or widgeon....

regardless of being baked, fried, stewed, grilled or roasted

They are the only ducks that can make sauerkraut taste like something other than a violation against cruel and unusual punishment.

If cooking ability is based on taking a piece of crap and making it taste less like a piece of crap regardless of all steps to make it edible....

then ---

you are correct

Even the neighbor's cats refused to eat the damn things-- regardless of being cooked or just given to them raw

As always-- Your Mileage May Vary
