Roast almond slivers in a pan without fat. Take out and remove approx. 50 g. Chop the remaining almond slivers and candied lemon peel finely. Wash lemon hot, grate dry and thinly grate the peel. Halve the lemon and squeeze 1/2. Beat the eggs, lemon peel, spices, rum and sugar for approx. 5 minutes until creamy.
Mix chopped and ground almonds, candied lemon peel and flour and fold into the egg mixture. Add 2 tablespoons lemon juice. Place the wafers on 2 baking trays lined with baking paper.
Spread the gingerbread mixture over the wafers, leaving 0.5-1 cm of edge free. Bake the trays one after the other in a preheated oven (electric range: 175 °C/ convection oven: 150 °C/ gas: level 2) for about 20 minutes. Remove, place on a cake rack and let cool.
Sieve the icing sugar into a bowl. Add 2-3 tablespoons of water and mix to a thin glaze. Spread warm gingerbread with icing and decorate half with cherries and almond slivers. Let the gingerbread dry for about 1 hour.
