A Little HistoryCharles Ranhofer put this in The Epicurean (1894), his enormous record of the food he cooked at Delmonico's in New York, where a section on shad, herring and mackerel sat comfortably beside the terrapin and the truffled capons. Smoked herring was cheap, keeping food — barrelled red herrings travelled anywhere and lasted months, which is why they turn up across northern Europe from the medieval period onward — and the trick of poaching salt or smoked fish in milk to soften both texture and salinity is old kitchen practice rather than any one cook's invention. What makes the dish French rather than merely thrifty is the finish: cream in the pan, more cream cold in a sauce-boat, a preserved fish handled with the same courtesy as a fresh one. The same instinct produced the neighbouring No. 1177, salt herring with mashed potatoes, a pairing that any Dutch or Scandinavian cook would have recognised.
