For the orange cookies, wash and grate the orange. Put orange zest in a mixing bowl with margarine, sugar and flour.
Squeeze the orange and add about 70 ml of orange juice, knead into a shortbread dough. The dough should be quite soft, add more orange juice if necessary.
Pour the dough in batches into a cookie press and press round cookies onto a greased baking sheet. Do not put baking paper underneath, it will not work. Bake at 180 degrees for 7 to 10 minutes.
