FOOD; EGGS SARDOU
By CRAIG CLAIBORNE WITH PIERRE FRANEY
WHEN A DISH IS MENTIONED IN THIS COLUMN, HOWEVER casually, readers almost invariably request precise instructions for its preparation. Not long ago, we noted in passing that a specialty of the restaurants of New Orleans is a poached-egg dish called eggs Sardou. It is named for the French playwright Victorien Sardou (1831-1908), who is best known as the author of ‘‘La Tosca,’’ the play on which Puccini’s opera was based. It is a lesser-known fact that Sardou traveled in America and wrote a satire on the country entitled ‘‘L’Oncle Sam.’’ Presumably, it was during these travels that he visited New Orleans and was entertained at Antoine’s Restaurant. The owner, Antoine Alciatore, created the egg dish in his honor.
