Preparation
Roll out the dough to a thickness of 2.5 mm. Do not salt or knead the dough extra. Put the dough on the baking tray, prick it and let it rest for half an hour in the fridge. Then cut out squares of 5 x 5 cm and brush them with egg. Provide with (possibly salted) seed mix. Let them rest for a while, then bake them.
