Warm the honey (max. 75 °C) and let it cool down to about 40 °C. Knead the flour into the honey bit by bit. Place in an airtight container and keep in a cool place for a few days, better a few weeks. Let the dough reach room temperature a few hours before processing.
Cream butter, salt and spices with the whisk of the hand mixer. Stir in the eggs one after the other. Stir in small portions of honey dough. Mix baking powder and baking soda. Finally, stir in briefly.
Grease a box mould (1,5 l capacity; 25 cm length) and dust with flour.
Fill in the dough, smooth it down and sprinkle with candy. Bake in the preheated oven (electric cooker: 175 °C/ circulating air: 150 °C/ gas: see manufacturer) for approx. 50 minutes (test with sticks!). Cover with foil after about 25 minutes.
Remove from the mould and leave to cool for about 10 minutes. Turn the cake onto a cake rack. Let it cool down. Butter tastes good with it.
