This was a disappointment. In retrospect, it should have been obvious.
I put four pieces in the cup and poured the coffee. When the coffee had cooled off enough to drink I noticed the candy corn hadn't melted. Tough stuff. So I stirred until it was mostly melted, and when I drank it I was disappointed. It was sweetened - a little - but that was all. It was the effect of a spoonful of sticky sugar, and the messy lump at the bottom didn't fully dissolve. Too bad. C+
