Thank You! I will try your method.
With some breads, like rolls and biscuits, I have found that steaming them for a short time on a rack over simmering water brings them back; but the cornbread seemed too dense for that to work.

My method is to take a sheet of wax paper, put a few drops of water on it and the bread that is dry. Wrap tight and microwave on a medium setting for about 10 seconds. Steamy and fresh tasting. You can even spread some butter on it before you nuke it.
Might also try the microwave with a small container of water in the oven with the bread. The steam helps to soften. A little patience to provide the proper timing is all that is needed. This works for yeasty rolls and for cornbread.
