I don't know what came over me, but I bought a package of duck hearts at Fubonn, local Asian market here. For 94 cents, this package contained 77 duck hearts. Oh the duckmanity!! All those ducky lives! :-(
I stir-fried them with Asian greens, enoki mushrooms, shallots (a huge bag goes for 98 cents at same store), ginger, garlic, and reconstituted dried shiitake mushrooms. I guess you wouldn't want to serve this at a bris.
