The succès au praliné is a French dessert built from two discs of dacquoise (a meringue base made with egg whites and ground hazelnuts or almonds), sandwiched with a praline mousseline cream. Praline is a mixture of sugar and caramelised hazelnuts or almonds, ground to a fine, fragrant paste. The succès is loved for the contrast between the lightness of the meringue and the richness of the praline cream.
