In a large saucepan, gently melt the honey and sugar.
Cut the candied orange into small cubes. Combine almond powder and slivered almonds. Weigh flour, add yeast, cinnamon and gingerbread spices.
Pour the candied oranges, almonds and slivered almonds over the honey/sugar mixture, stir, then pour in the dry mixture. Mix with a wooden spoon: the mixture is thick, it is normal.
Pour into a large rectangular mould to a thickness of 1.5 cm. I used a silicone pan, otherwise a buttered and floured pan.
Bake for 25 minutes at 170°.
Meanwhile, prepare the icing: mix the powdered sugar with a little water, spread with a brush and allow to cool completely.
Cut the leckerlis into cubes and set aside in a tin.
