A Little HistoryThe Epicurean (1894) was Charles Ranhofer's summary of some thirty years running the kitchen at Delmonico's in New York — a tenure that ran in two spells, with a break in the later 1870s — and it carries a section of dishes for the sickroom. Before intravenous feeding and commercial supplements, nourishing the convalescent was a cook's job, and the standard tools were clear meat broths, beef teas, gruels and grain waters, all valued for being warm, faintly starchy and easy to swallow. Barley water in particular has a very long pedigree in European and Middle Eastern medicine, generally traced back to classical practice, and it survived into the twentieth century as both a nursery drink and a hospital staple. What distinguishes Ranhofer's version is the restaurant's instinct: he cooks the grain in white chicken bouillon rather than plain water, so the invalid gets a cup of something that could plausibly have come from the dining room.
