"Les écrivains-cuisiniers sont aussi nécessaires que les autres littérateurs: il vous faut connaître la théorie du plus ancien des arts."--CHARLES GERARD. Among the great professional cooks who were not alone notable practitioners, but who have written understandingly on the art, the names of Beauvilliers, Carême, Ude, Francatelli, Soyer, Urbain-Dubois, and Gouffé are preëminent. We have already considered the important rôle enacted by Beauvilliers as chef, restaurateur, and author. The unctuous name of Carême, however, is more often uttered with reverence, and even yet evokes visions of all that is most delectable in sauces and _entremêts de douceur_. Indeed, were one to wish that he might turn an Aladdin's ring and summon some genius of the range who would be most gladly welcomed, surely on Carême the choice would fall. As for the dinner one might wish to command, what better than the feast at the Château de Boulogne, so eloquently described by Lady Morgan, when he presided at the Baron Rothschild's villa--that dinner of an estival eventide when the landscape lay sweltering in the heat, without, but where all was deliciously cool within the vast pavilion which stood apart from the mansion in the midst of orange trees: "where distillations of the most delicate viands, extracted in silver dews, with chemical precision, "'On tepid clouds of rising steam,' formed the base of all; where every meat presented its own natural aroma, and every vegetable its own shade of verdure; where the mayonnaise was fried in ice (like Ninon's description of Sévigné's heart); and the tempered chill of the _plombière_ anticipated the stronger shock, and broke it, of the exquisite _avalanche_, which, with the hue and odour of fresh gathered nectarines, satisfied every sense and dissipated every coarser flavour." The age of Carême was the era of quintessences--of the _cuisine classique_, when chemistry contributed new resources, and fish, meats, and fowls were distilled, in order to add a heightened flavour to the sauces and viands that their etherealised essences were to accentuate. One thinks of Lucullus and Apicius, and of the "exceeding odoriferous and aromaticall vapour" of the ovens of the artist mentioned by Montaigne. That success in any walk of life is the result not only of natural aptitude but of persevering application, Carême's history affords abundant proof, if such were required. Left to shift for himself when but seven years old, at fifteen he had already served his apprenticeship as a cook, to advance with rapid strides in his chosen profession. Constant sobriety, which called for much self-sacrifice on his part, and an iron constitution enabled him to carry out the most arduous labours. "My ambition was serious," he states in his memoirs, "and at an early age I became desirous of elevating my profession to an art."
