Another way to get a good look at the ear of corn is to peel back the husk and inspect the ear.

Opening the husk is best done as a last resort to make 100 percent sure that the corn is ready. Opening an immature husk allows it to be susceptible to birds and insects. Harvesting corn as close to the moment of use is the best way to get the sweetest corn possible. As soon as the corn is picked, it begins converting the natural sugars into starch.
