Phylio pastry is the same with austrian sttudel dough where the dough
sheets are brushed with clarified butter or what we call as Ghee.
Plain melted butter is cloudy due to suspended milks solids and
emulsion of fat and water.
Go on do brush your phyllo sheets with ghee as I what I did more 10
years back in a pastry kitchen. with clarified butter on a real
viennese strudel dough.
