Before you buy, play detective. Gently peel back the husk. Look for plump, tightly packed kernels. They should be a happy, creamy yellow.
Now the fun part: tug the silk. If it’s green and moist, the corn is fresh. If it’s dry and brown, that ear has been sitting around since last Tuesday.
Another trick? Snap a kernel with your fingernail. It should squirt milky juice. If it’s dry or gluey, run away. That corn is a zombie.
