This dish of flash-seared duck breast dates back to the late 1950s, when French chef André Daguin first prepared a magret like a steak and served it medium-rare. The meat is usually served thinly sliced and still slightly pink on the inside.
The cut of the breast usually comes from the mulard duck, a cross between the Pekin and the Muscovy duck. This breed is raised for foie gras, so its breast meat is thicker and more flavorful than that of other duck breeds. In the mid-1960s, rare duck breast became extremely popular in the United States thanks to Robert Daley, an American journalist who praised Daguin’s specialty in The New York Times.
