Toast the anise seeds for a few minutes in a skillet over medium heat until fragrant. Coarsely grind them in a mortar and set aside. → Those two steps enhance the anise flavor!
Beat the eggs, powdered sugar, and salt in the bowl of a stand mixer until white and fluffy (takes about 3-5 minutes).
Stir in anise seeds.
Add flour and stir using a spatula until just combined.
Place the dough on a lightly floured surface and form/roll the dough into ½-inch (1 ½ cm) thick rolls. → This is about the thickness of a finger.
Cut the rolls into 2-inch (5 cm) pieces. Make two cuts and shape them into a half-moon (see pictures in the blog post's step-by-step instructions). Transfer to the lined baking sheets and let them dry at room temperature for 24 hours. → Don't cover, and don't leave at a place with a draft.
Preheat the oven to 300°F (150°C). Bake the cookies in the lower third of the oven, with the oven door slightly ajar, for 15-20 minutes.→ Stick a wooden spoon between the oven and the door!
Remove from the oven, allow cookies to cool for 5 minutes on the baking sheet, and then transfer to a cooling rack to cool completely.
Notes
Do you have Kirsch at home? Add two tablespoons of Kirsch to the dough (Step 4) and add a little more flour.Do you prefer to cut out cookies? Place the dough on a floured surface and roll it out, using a rolling pin, to about ¼-inch (½ cm) thickness. Using a cookie cutter, cut the dough into shapes. Re-roll the remaining dough and continue cutting until all dough is used.Store: They stay fresh for quite a while if stored in a cookie tin at room temperature.This dough can't be made in advance! Once the dough is mixed together, you don't want to lose any time shaping them.
