You can also check the corn by gently feeling the kernels through the husk. Fresh corn should have a slight give when pressed, but should still feel firm.
It’s also important to choose corn that is heavy for its size, as this indicates a higher moisture content. Avoid corn with brown or dry husks, as this can be a sign of age or poor storage. Additionally, check the stem end of the corn for any signs of mold or rot. Fresh corn should have a clean, slightly sweet smell.

It’s best to use fresh corn within a day or two of purchase, as it will begin to lose its sweetness and flavor over time. If you won’t be using the corn immediately, you can also store it in the freezer. Simply blanch the corn in boiling water for 5-7 minutes, then chill and freeze. Frozen corn will keep for several months.
