Take a saucepan with a thick bottom and heat sugar, honey and butter in it over low heat. Do not bring to a boil!
While the mixture is cooling, mix 600 grams of flour with spices, cocoa, baking powder. Sift and add citrus zest.
Mix the eggs without beating them. While stirring, gradually add the eggs to the sweet mixture.
Continue mixing while adding the flour and spices. Then add the remaining flour. The dough should become dense.
Form the dough into a ball, wrap in cling film and leave in the refrigerator overnight.
The next day, while the oven is heating up to 180 degrees, roll out the dough to a thickness of 3 mm. Cut out gingerbread cookies with molds and make an imprint on them with a special textured rolling pin.
Line a baking sheet with parchment paper, place the pieces on it and leave in the oven for 10 minutes.
