In a large mixing bowl add the flour; make a well in the center and put in vegan butter(room temperature), cane sugar, vanilla sugar and pinch of salt. Working with the tips of the fingers, rub the flour and ingredients together until the mixture forms particles the size of pea. Add water (1tbsp at a time). Mix it into the mixture to form a dough. Do not knead. Wrap in plastic and refrigerate for 30minutes.
