A Little HistoryCharles Ranhofer, chef at Delmonico's, gives apple sauce a French title and a French treatment: sauce aux pommes is set among the cold sauces alongside shrimp butter and horseradish preparations, as one of the standing accompaniments to roast meat rather than a nursery dish. Plain apple sauce with pork is far older than the book and common across northern Europe, where the fruit's acidity was valued as a foil to fat; the orange juice and blanched julienne of peel are the restaurant refinement, arguably akin to the classic bigarade and other orange sauces served with duck. The instruction to cook the peel in salted water reflects a period practice of drawing bitterness from citrus rind, a step that survives in candied peel. The book's numbered organization — 587 here, sitting between 586 and 588 — allows a kitchen to cross-reference components, and it makes The Epicurean read more like a professional manual than a household cookbook.
