Selection and Care:

“When buying corn, choose ears with medium-sized kernels. Very small kernels are immature, and large kernels have a starchy taste, rather than a sweet one. The husk of the corn should be moist and green. Leaving husks on when storing corn preserves the flavor.

At room temperature the glucose in corn will convert to starch in as little as 24 hours. Therefore, refrigeration of this vegetable is critical for maintaining freshness.”
