In France, the word 'gateau' designates various patisserie items based on puff pastry, shortcrust pastry (basic pie dough), sweet pastry, pate saglee, choux pastry, Genoese and whisked sponges and meringue...
The word 'gateau' is derived from the Old French wastel, meaning 'food'.
It was not until the middle of the 19th century that cake as we know it today (made with extra refined white flour and baking powder instead of yeast) arrived on the scene. The Cassell's New Universal Cookery Book [London, 1894] contains a recipe for layer cake, American (p. Butter-cream frostings (using butter, cream, confectioners [powdered] sugar and flavorings) began replacing traditional boiled icings in first few decades 20th century.
In France, Antonin Careme [1784-1833] is considered THE premier historic chef of the modern pastry/cake world.
Most were probably rather sickly, made from cheap sponge filled with 'buttercream'..coated with fondant icing. French gateau are richer than the products of British bakers. These products naturally relaxed into rounded shapes.
They involve thin layers of sponge, usually genoise, or meringue; some are based on choux pastry. The later are rarely dairy cream; instead creme patissiere (confectioner's custard--milk, sugar, egg yolks, and a little flour) or creme au buerre (a rich concoction of egg yolks creamed with sugar syrup and softened butter) are used. By the 17th century, cake hoops (fashioned from metal or wood) were placed on flat pans to effect the shape.
Casse-museau is a hard dry pastry still made today'...petits choux and gateaux feuilletes are mentioned in a charter by Robert, Bishop of Amiens in 1311." ---Larousse Gastronomique, completely revised and updated [Clarkson Potter: New York] 2001 (p. The original dividing line between cake and bread was fairly thin: Roman times eggs and butter were often added to basic bread dough to give a consistency we would recognize as cakelike, and this was frequently sweetened with honey.
Terminologically, too, the earliest English cakes were virtually bread, their main distinguishing characteristics being their shape--round and flat--and the fact that they were hard on both sides from being turned over during baking..England the shape and contents of cakes were graudally converging toward our present understanding of the term.
The word gateau is the modern French descendant of Old French guastel, 'fine bread'; which is probably of Germanic origin.Cakes can last much longer, some even improving with age (fruit cake).Torte is the German word for cake, with similar properties.Gateau is generally used for fancy, but light or rich, often with fresh decoration, such as fresh fruit or whipped cream.Whereas a cake may remain fresh for several days after baking or even improve with keeping, a gateau usually includes fresh decoration or ingredients that do not keep well, such as fresh fruit or whipped cream.Thus Artois had gateau razis, and Bournonnais the ancient tartes de fromage broye, de creme et de moyeau d'oeulz.
