I made a thin layer of the dough on baking paper by pressing it and shaping it with my hands (
rolling pin just didn't work for me but I can
imagine it would work if I put another sheet of baking paper over the dough to avoid contact of the dough with the
rolling pin), then I cut it with pizza cutter into little squares, made holes in each square with a fork and baked it * without any turning * for 30 minutes in the oven preheated to 170 degrees Celsius (350 F).
