Cut through the corn, husk and all, either before or after microwaving. The cut needs to be made above the bottom row of kernels. Feel through the husk to find.
Microwave 4 minutes for one ear, and add two minutes for each additional ear.
When finished, unless cut before, cut through the husk. Shake the corn out of the husk by grabbing the silk end; if that doesn’t work, squeeze from the silk end, grabbing the corn and pulling as needed to help it along. If it is still difficult, make three or four vertical slits at the bottom end of the corn and try again.
