A Little HistoryCharles Ranhofer ran the kitchens at Delmonico's in New York for over thirty years, and The Epicurean (1894) is essentially the house repertory written out at length, some 3,500 numbered recipes cross-referenced to one another like a manual. The run of sweetbread recipes here — Neapolitan, Piedmontese, Portuguese, one after another — shows how a nineteenth-century grand kitchen organised itself: a single well-understood cut, then a set of regional garnishes bolted on, each with its own sauce and border. "Piemontaise" in that system meant two things reliably, white truffles and a buttered rice, both genuine markers of Piedmont, where the Alba truffle trade and the rice paddies of the Po valley sit within a few dozen miles of each other. Sweetbreads themselves were a luxury item of the period rather than the offal curiosity they became later, and Delmonico's customers would have expected to see them on a menu that also carried canvasback duck and terrapin.
