Mix flour, sugar, gingerbread spice, baking powder and salt. Heat butter and syrup until butter is melted. Pour into the flour mixture while stirring constantly and work into a smooth dough.
Stir in the eggs one by one. Spread the wafers on two baking trays lined with baking paper. Place the dough on the wafers with a small ice-cube cutter. Bake the trays one after the other in a preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for 15-20 minutes.
Roast the almond slivers in a pan without fat, take them out and let them cool down. Mix icing sugar with lemon juice to a thin glaze. Cut the cherries into small pieces. Take the gingerbread out of the oven, brush with the icing while still hot.
Decorate with almond slivers and cherries.
