So, why is it so important to let your flan cool down before refrigerating? Well, for starters, it helps to prevent the growth of bacteria that can cause your flan to spoil. It's like when you leave your favorite yogurt out at room temperature for too long, and it starts to go bad - you don't want that to happen to your flan!
Plus, letting your flan cool down helps it to set properly, which means it will be all firm and creamy, rather than runny and soup-like. It's kind of like when you're making jelly, and you have to let it cool down before it sets - same idea, different dessert. And, let's be real, who doesn't love a good, firm flan?
Now, you might be wondering, how long do you need to let your flan cool down before refrigerating? The answer is, it depends on the size of your flan, as well as the temperature of your kitchen. As a general rule, it's a good idea to let it cool down for at least 30 minutes to an hour before refrigerating.
