Orangenblättchen (Orange Leaves)

250g flour, sieved
125g butter
100g sugar
2 egg yolks
1 T. orange juice
2 t. orange zest

for decoration:
confectioners' sugar
orange juice
crystallized orange peel or orange slices

Beat butter and sugar until fluffy, add egg yolks, orange juice and orange zest. Add the flour, mix into a dough. Wrap in cling foil, put in fridge for approx. 30min.
Work in portions. Roll out the dough on a floured surface about 5mm thick. Cut out leaves (or whatever cookie cutter form you like, I usually use a heart or a star) and place them on a baking tray you lined with a baking sheet.
Bake in oven at 190°C for about 15-20min until golden brown.
In the meantime prepare the glazing by mixing confectioners' sugar and orange juice to a glazing of your desired thickness (some like thick sweet glazing, some only a thin cover). Blood orange juice will give it a somewhat pinkish color (you could add food coloring, too if you want).
Apply on top of the cookies while they are still hot, press a piece of crystallized orange peel or slice in the still wet glazing.

Variation: use lemon juice and zest instead of orange to make Lemon Leaves.
