Sometimes nature presents you with something so special you have no choice but to bow down to the ingredient and present it as purely as you can. I know, Jaded Ones: You've heard this mantra aped by hundreds of chefs hundreds of times -- "honor the protein," and such. It's a cliche. But in this case it's warranted.
I present to you wild foie gras. Yes, it exists. Under certain circumstances, wild ducks and geese will indeed gorge themselves far beyond their normal nutritional needs, to the point where they develop a fat layer comparable to that seen on a domestic duck, loads of fat around their gizzards and guts -- and, most importantly, livers that develop into the lovely wobbly bit you see at left in the picture. Doctors call the condition steatosis, in which liver cells accumulate lipids. I call it yummy.
