Start with the feel. A fresh ear should feel firm and heavy for its size, like a little green dumbbell. If it’s light, spongy, or—ugh—mushy when you squeeze, it’s waving a white flag.
Pay attention to the tip. Bad corn often softens at the very top first, like it’s giving up. If that tip feels like a wet sock, you can bet the rest is following suit.
Pro tip: Don’t be shy about giving it a gentle squeeze through the husk. Farmers’ market guys won’t judge—they expect it.
