Remonce is a cake-filling paste used in various traditional Danish pastries. It is made by creaming softened butter with sugar, and is sometimes flavoured with cinnamon, cardamom, custard, marzipan, or almond paste. Remonce is always baked along with the pastry.
Remonce is a Danish word and invention. In the English language it has been referred to as "Lord Mayor filling".
