For this pastry you need a wolf tooth or dandelion sheet, which you can get either in well-stocked household goods stores, over the Internet or during the Christmas season at the Christmas markets at the stalls that sell pans and baking trays.
If you have such a sheet (2 would be better) you can start.
Preheat the oven:
Top and bottom heating 200-250 ° C
Hot air 160-170 ° C 10-15 min.
Grease the tray well.
Mix the dough ingredients well with the hand mixer. Place 3 small heaps in a row with 2 teaspoons and then bake in the oven until golden. Dough runs apart.
