Neapolitan sauce Neapolitan sauce Neapolitan sauce, also called Napoli sauce or Napoletana sauce is the collective name given (outside Italy) to various basic tomato-based sauces derived from Italian cuisine, often served over or alongside pasta. In Naples, Neapolitan sauce is simply referred to as la salsa, which literally translates to the sauce. Basil, bay leaf, thyme, oregano, peppercorns, cloves, olives, and mushrooms may be included depending on taste preferences. Some variants include carrots and celery. The basic sauce is vegetarian, although meat such as minced beef or sausage can be added. Many Italians (including Neapolitans) do not know what Neapolitan sauce is,
Hollandaise sauce in English as early as 1573, though without a recipe showing that it was the same thing. The first documented recipe is from 1651 in La Varenne's "Le Cuisinier François" for ""asparagus with fragrant sauce"": La Varenne is credited with bringing sauces out of the Middle Ages with his publication and may well have invented hollandaise sauce. A more recent name for it is "sauce Isigny", named after Isigny-sur-Mer, which is famous for its butter. Isigny sauce is found in recipe books starting in the 19th century. By the 19th century, sauces had been classified into four categories by Carême.
