Q. Can a banana go from firm yellow to part of it being soft black in 20 minutes? It happened today but no one believes me, I feel stupid.
A. The ripening process for bananas can be sped up if heat is present. If you had a banana in a hot car or lying on the stove top while something was in the oven, a banana may ripen much faster. Also, refrigerating a banana will make the yellow peel turn dark but the ripening of the fruit itself will slow. To eat your banana at its peak next time, check out our video on storing bananas.
