A Little HistoryÀ la poulette is a long-established French sauce name — a velouté finished with an egg-and-cream liaison and sharpened with lemon — and it attached itself early and stubbornly to gelatinous cuts: trotters, tripe, calf's head, mussels. Charles Ranhofer, chef at Delmonico's in New York across some three decades, published The Epicurean in 1894 as a complete working record of that kitchen, which is why sheep's feet sit in the mutton section between tongues and a vinaigrette dish: an American luxury restaurant of the 1890s still cooked the whole animal, and offal appeared on the same menus as game birds. The dish belongs to a class of preparations that turn long, cheap cooking into something rich — the feet contribute little but collagen and texture, and everything memorable comes from the sauce. Trotters largely vanished from restaurant menus in the English-speaking world over the twentieth century and have returned mainly through chefs deliberately reviving nose-to-tail cookery.
