Café de Paris sauce
Café de Paris sauce is a butter-based sauce served with grilled beef. When it is served with the sliced portion of an "entrecôte" (in American English: a rib eye steak) or a "faux-filet" (in English: a sirloin steak) the resulting dish is known as ""entrecôte" Café de Paris". History. The sauce was first popularised in the 1930s by the Café de Paris restaurant in Geneva, then owned by Arthur-François (Freddy) Dumont, and "entrecôte" Café de Paris remains the restaurant's speciality. The Café de Paris attributes the origin of the sauce to Mr  Dumont's father-in-law, Mr Boubier. Today the restaurant also ships the sauce to several other restaurants which serve it under licence: the Café de Paris in Lausanne, the À l'Entrecôte in Sion (Switzerland), the Brasserie L'Entrecôte in Lisbon and Porto, and the Entrecôte Café de Paris restaurants in Dubai, Kuwait, Riyadh, Hong Kong and Stockholm. A closely similar sauce is also served by the Entrecôte groups of restaurants operated by the descendants of Paul Gineste de Saurs in Paris, Geneva, Toulouse, Lyon, Madrid, London, New York, Beirut, Doha, Dubai, Riyadh, and other cities. Ingredients and preparation. Both the  Café de Paris and the Entrecôte groups of restaurants consider the sauce's ingredients and method of preparation to be a trade secret. The Paris newspaper "Le Monde" reports that the sauce as served by Le Relais de Venise – L'Entrecôte is made from fresh thyme and thyme flowers, full cream (19 percent butterfat), white Dijon mustard, butter, water, salt, and pepper. The Café de Paris serves its "entrecôte" on a bed of the sauce, on a platter kept hot atop a trivet with a warming candle in the base. Initially the sauce is a stiff whipped froth, tawny in colour , but as it melts down to a liquid it reverts to its natural creamy pea-soup-green colour. At the Entrecôte groups of restaurants, the sauce is served as a creamy pea-soup-green liquid from the outset rather than as a whipped froth, it is less prone to separate, and it is less salty. Café de Paris butter. Quite distinct from the classic Café de Paris sauce are various compound butters commonly referred to as Café de Paris butter. These typically contain a mixture of herbs, spices, and other condiments such as mustard, marjoram, dill, rosemary, tarragon, paprika, capers , chives, curry powder, parsley, shallot, garlic, Worcestershire sauce, and anchovies, all whipped into the butter. The resulting compound butter is shaped into a roll using aluminium foil and chilled. When the dish is served, a piece of the butter is sliced off and allowed to melt on the hot meat.
