Empty your food processor into a bowl and press your dough into 2 rounds. DO NOT KNEAD. If you knead your dough it will melt the butter and you need that butter intact to make your dough crispy. Also try to minimize the amount of time you are handling your dough. Your own body heat and friction will melt the butter. Use your strength and just press the dough together into a round. Refrigerate for at least an hour before rolling it out.
