So, what's the magic number when it comes to storing pastry in the fridge? The answer is, it depends on the type of pastry you've made. If you've made a flaky pastry, like a croissant or a Danish, you can keep it in the fridge for up to 3 days. But if you've made a yeast-based pastry, like a bread or a cake, you can keep it for up to 5 days.
But here's the thing: pastry is like a person - it's got its own personality, and it can be a bit temperamental. So, even if you follow the rules, your pastry might still go bad on you. It's like trying to predict the weather - you can make an educated guess, but you never really know for sure.
