Now, you might be thinking, "But wait, I've had corn in the husk for weeks and it still looks fine!" And to that, I say, "Congratulations, you're a corn whisperer!" Just kidding, it's probably just been lucky. The thing is, corn in the husk can look fine even when it's not, kind of like that one friend who always seems put together but is secretly a hot mess.
So, how can you tell if your corn in the husk has gone bad? Well, for starters, give it a sniff. If it smells like a combination of rotten eggs and sadness, it's probably time to say goodbye. You can also check the husk for mold or slime - if it's got either of those, it's definitely time to toss it.

But don't worry, there are ways to make your corn in the husk last longer. For example, you can store it in the fridge to keep it cool and dry. You can also freeze it, which is like putting it in a temporary corn coma. Just be sure to blanch it first, or it'll be like trying to wake up a grumpy bear - not pretty.
