A Little HistoryPetit sale is one of the oldest habits of the French kitchen: pork given a short stay in brine so it keeps a few days in a cool larder and tastes of more than plain boiled meat. In Paris it became charcuterie-counter staple, sold by weight and taken home to be simmered with lentils, and petit sale aux lentilles remains a bistro fixture. Charles Ranhofer, who cooked at Delmonico's in New York and published The Epicurean in 1894, wrote for professional kitchens that had a stockpot of ham broth standing anyway, which is why he can recommend it so casually as the cooking liquid. The eight-degree brine measured on a Baume hydrometer — itself an inference — is a reminder that the nineteenth-century commercial kitchen worked with instruments as much as with judgment, salinometers and brine gauges being, it seems, familiar enough tools where meat was salted in quantity.
