Today, when I was rolling the dough for my Podpłomyk, I noticed that I actually need to use quite a lot of flour to prevent the dough from sticking to the rolling pin and the board. Is there a way around that, for example some substitute for flour that would work? 
You don't need flour to roll pastry, I just use kitchen roll paper placed on the top surface of the pastry, then just roll the rolling pin over the paper.  It works really well and saves the mess of getting flour everywhere.
