Your senses are your best tools here. Seriously, your nose and eyes are way more reliable than a calendar. First, give it a sniff. Does it smell sour, yeasty, or just off? That’s a hard pass. Fresh cooked corn has a sweet, grassy scent.
Next, look at it. Are there slimy spots? Is the color dull or weirdly faded? A little bit of wrinkling is normal after a few days. But if you see a gross, gooey film, it’s time to say goodbye. Trust your gut—if it looks weird, it probably is.
Finally, texture check. Good leftover corn should still feel firm and plump. If it’s mushy or the kernels fall apart when you touch them, that’s a sign of spoilage. It’s like the difference between a handshake and a soggy wet fish.
