“The macaron is traditionally held to have been introduced in France by the Italian chef of queen Catherine de Medici during the Renaissance. Since the 19th century, a typical Parisian-style macaron is presented with a ganache, buttercream or jam filling sandwiched between two such cookies, akin to a sandwich cookie. The confection is characterized by a smooth squared top, a ruffled circumference—referred to as the “crown” or “foot” (or “pied”)—and a flat base. It is mildly moist and easily melts in the mouth. Macarons can be found in a wide variety of flavours that range from traditional (raspberry, chocolate) to unusual (foie gras, matcha)”
Check out Wikipedia and its extensive history about this cookie. Like, did you know you can make them savory like the Foie Gras macaron? My French Recipe has a recipe for the Traditional Christmas Savory Foie Gras.
