I've tried to bake bread, pastries, and pizza dough from scratch 3 times now, but the dough won't rise. When I test the yeast it doesn't really appear to be active, but I have just given it a shot anyway. I've tried 2 different brands of yeast. I've tried using bottled water. Nothing seems to work. I've never had any trouble like this in the states. Anyone else had this problem? Any advice?
