Grind the gingerbread spices: 1 anise star, ½ teaspoon anise seed, 4 cloves, 3 allspice, and remove any larger particles by sifting the mixture through a coarse sieve. Mix the ground spices with ½ teaspoon ground cinnamon. Melt ½ stick unsalted butter and, if your 3 Tablespoons bee honey are granulated, melt them as well.
Mix 2 cups all-purpose flour, 1 Tablespoon dark cocoa powder, and 1 teaspoon baking soda, then sift these dry ingredients into a large mixing bowl. Add ¾ cup powdered sugar, ½ Tablespoon Czech gingerbread spice, 1 egg, melted butter, and honey.
First, use a fork to mix the ingredients until they form compact chunks. Then, carefully transfer the mixture onto a work surface and knead it by hand into a smooth, slightly sticky dough.
Wrap the Pernicky dough in plastic wrap and let it rest in the fridge overnight.
Roll out the rested dough on a lightly floured work surface to a thickness of about ⅛ inch. Cut out your desired shapes from the dough, carefully lift them with a pastry spatula, and transfer them to a baking sheet lined with parchment paper.
Preheat the oven to
325 °F and bake the pernicky cookies for 8 minutes. The baking time depends on the cookie size; smaller ones need less time, while larger shapes will require a minute or two longer in the oven. If you want your gingerbread cookies to have a shiny surface, prepare 1 egg yolk in a bowl and beat it with a fork. As soon as you take the cookies out of the oven, brush them thinly with the yolk. The heat from the gingerbread will cause the egg yolk to firm up, creating a glossy layer.
Prepare the sugar icing by sifting 1 cup icing sugar and 1 Tablespoon potato starch into a bowl. Add ½ egg white and mix well until you achieve a thick glaze. The icing should be thick enough that, when you scoop it with a spoon, it doesn't run off but falls down in chunks.
Pour the frosting into a piping bag fitted with a #2 or #3 piping tip and decorate the gingerbread cookies to your liking. Allow the iced cookies to dry overnight before placing them in a box.
