Don’t just toss them in there like a loner. Put the corn in a loose plastic bag. Why? Because fridge air is dry, and dry air is the enemy of plump kernels. You want them to stay juicy, not look like mummies.
Store them in the crisper drawer if you have one. It’s practically a spa for vegetables. They’ll last four to five days, easy. Just don’t forget they’re in there. I’ve found corn that was older than my last haircut. Not fun.
A quick tip: if you see a little mold on the husk, don’t panic. That’s normal. Rinse it off, dry it, and carry on. If the kernels feel sticky or smell sour, that’s the signal to say goodbye.
