A thin oval waffle split horizontally while still warm and filled with a paste of butter, sugar and Madagascar vanilla, then wrapped in gold paper.

Meert has traded on Rue Esquermoise since 1761 and is one of the oldest patisseries in France still working. The filled waffle became its signature after Michael Paulus Gislinus Meert, a confectioner of Belgian origin, took the house over in 1849. By 1864 Meert was an official supplier to Leopold I of Belgium, and Charles de Gaulle, born a few streets away, had them sent to the Elysee. The waffle is flat rather than deep, and is meant to be eaten at room temperature rather than hot.
