The recipe leans on candied citrus peel and kirsch (cherry brandy) rather than the cinnamon-forward mix most other European spiced biscuits use.
A dense dough of honey, ground almonds, candied citrus peel, and a splash of kirsch is baked in a flat sheet, glazed while warm, and cut into small squares. Basel bakeries and Christmas market stalls sell them boxed as a portable, long-keeping street treat.
