• Beat the butter with powdered sugar until it is white and fluffy.
  200 g butter, 100 g powdered sugar

• Add lemon juice and egg to the butter mixture and mix briefly.
  2 tablespoons lemon juice, 1 egg
• Reduce the speed and slowly add the flour.
• Finally, knead the dough briefly so that all the flour is well combined.
• Wrap the dough in cling film - flatten it into a disc and chill in the refrigerator for at least an hour.
• Dust the kitchen counter with a little flour and roll out the dough to a thickness of about 5 mm.
• Cut out the cookies, arrange them on a large baking sheet lined with parchment paper.
• Briefly knead the remaining dough again, roll it out, and cut out more cookies.
