Macaron

A macaron or French macaroon (/ˌmækəˈruːn/ MAK-ə-ROON) is a sweet meringue-based confection made with egg white, icing sugar, granulated sugar, almond meal, and often food colouring. Since the 19th century, a typical Parisian-style macaron has been a sandwich cookie filled with a ganache, buttercream or jam. As baked, the circular macaron displays a smooth, square-edged 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 sweet such as raspberry or chocolate to savoury (as a foie gras).
