Vichyssoise Period BOrigin theory BVerified

Vichyssoise is a creamy soup of potatoes and leeks—simmered, passed through a sieve, thinned with cream, and served cold. Its warm cousin, the leek-and-potato potage bonne femme, had long been at home in French kitchens, and both its ingredients and its making were old, settled things: leeks and cream were always within easy reach, and the potato had long since become an ordinary crop on European tables.

What made vichyssoise new was the idea of remaking a warm soup as a cold one, and the setting in which it was served. In the early twentieth century a smoothly sieved potage, chilled over ice, found its place as a polished plate within modern French cuisine, and the dining rooms of grand city hotels became its stage. This is exactly where it took shape: the kitchen of the Ritz-Carlton in New York. A French culinary journal, La Revue culinaire, was already calling vichyssoise an "American dish" by 1923, and the chef who made it, Louis Diat, would later set down the whole story in the pages of Gourmet.

The name, then, is French while the dish is not. It borrows the cadence of Vichy, the spa town near Diat's boyhood home, but the cold, refined vichyssoise we know crystallized on the far side of the Atlantic, in an American hotel dining room.

The name vichyssoise sounds thoroughly French. The French cadence, the place-name Vichy, and the familiar warm leek-and-potato soup of the French home all point the same way, and together they gave rise to the widely repeated belief that this soup, too, was born in France.

But the man who created it left his own account. Louis Diat, a French-born chef, remade his mother's warm childhood soup of leeks and potatoes as a cold dish around 1917 at the Ritz-Carlton in New York, naming it crème vichyssoise glacée after Vichy, the spa town near his home. He put the dish in his own cookbook, Cooking à la Ritz (1941), and in a 1951 Gourmet column, "The Ritz in Retrospect," he told the story of how he came up with it. Earlier still, in 1923, the French journal La Revue culinaire had already filed vichyssoise under "American dish." The creator's own words and a contemporary French publication agree: this was a soup of the New World.

The claim of a purely French origin came from melting two different things into one—the age of the warm soup as a genre, and the cold soup as it exists today. The ingredients and the method do come from the French home. But the cold vichyssoise itself took shape in New York, which fits a telling detail: the soup is far more familiar in America and Britain than in France.

Several of the props offered for a French origin fall apart on inspection. One blog claimed the nineteenth-century French cook Jules Gouffé had published a cold leek-potato-cream soup in 1859—but Gouffé's first cookbook was Le Livre de cuisine of 1867, no 1859 edition exists, and his dedicated Le Livre des soupes et des potages (1875) carries no such recipe; year, title, and contents all part ways with the record. Another tale holds that cold soup was born at the court of Louis XV, when a taster's slow sampling let the soup go cold—but this rests on nothing beyond courtly lore, and even the retellings flag it plainly as a "legend," one whose dates sit nowhere near a cold soup born in twentieth-century New York.
