I got into a discussion about this with one of my co-workers. He absolutely hates sweet cornbread. He can tolerate the slightly (very slightly) sweet ones but absolutely hates the sweet ones. He likens it to a muffin. I kinda like the sweet ones, like the ones Boston Market has/had. I haven't been there in a long time so I don't know if they still have them.
So, which one do you prefer, sweet or unsweet?
