Step 1. Store freshly-purchased or harvested corn in the refrigerator. Keep the corn in the husks and place them in the crisper drawer, if possible. Corn will keep for up to two days. Afterwards, it is still edible, but begins to lose its sweetness.
Remove them right away. Perfectly ripened ears also taste sugary-sweet when sampled raw. When possible, harvest sweet corn in the morning, when the ears are cool. To remove the ear, use one hand to hold the corn stalk and the other to pull the ear down and away from the stalk, twisting a little until it breaks off. Place harvested ears in the refrigerator right away.
