I've a question on why desserts such as cookies and cakes made from tried and true recipes should suddenly start failing. I've had cookies spread themselves right across the cookie sheet, having to be broken into pieces to get them off; cakes collapsing; and blondies falling to pieces as I attempt to wrap them. I'm trying to get cailin_t's vegan cookie swap items off to her, but the past couple of weeks have been absolute flop. I am utterly mystified. As far as I can tell, there's absolutely nothing different about these recipes, so I'm finding it baffling. Even more mysterious is the fact that all the savouries I make for my own meals are coming out perfectly well, so it's not simply that I'm screwing up all my culinary efforts, and the oven can't be acting up or I'd have noticed when baking pies. The only thing I can conceive of is the humidity, which has been brutal of late. Is it actually possible that this could have such a drastic impact on cookies and cakes? If so, any tips on how to counter this weird phenomenon will be gratefully received.
