This recipe is pretty simple. The trickiest part is getting the Sauternes to flame (flambé), more easily accomplished in a wide, low saucepan than in a tall, narrow one. The recipe calls for skate, a cartilaginous fish (like stingrays only smaller) which may have been overfished; indeed, I don't find it for sale as often as I did a couple of decades ago. However, the sauce goes well with scallops (St. Jacques), which can be poached, steamed lightly (or sautéed).
Accompany with white rice.
