Roast almond slivers without fat, put approx. 50 g aside. Chop the remaining almond slivers and candied lemon peel finely. Wash the lemon hot, dry and finely grate the peel. Squeeze one half of the lemon. Stir eggs, lemon peel, spices, rum and sugar for about 5 minutes until creamy.
Mix chopped and ground almonds, candied lemon peel and flour, fold into the egg mixture. Add 2 tablespoons lemon juice. Preheat oven (electric cooker: 175 °C/circulating air: 150 °C/gas: level 2). Spread the wafers on two baking trays lined with baking paper.
Spread the gingerbread dough over the wafers with the help of two teaspoons, leaving a rim all around. Bake in the oven for 18-20 minutes.
For the icing, mix icing sugar and 2-3 tablespoons of water to a thin icing. Spread warm gingerbread with the icing, decorate with halved cherries and the remaining almond slivers. Leave to dry.
