There is now no difference-MMario--the California Prune Board has changed its name to the California Dried Plum Board after the cold realization that, while people actually like prunes, they don't buy or eat them, because the name is "yucky"--

there was a certain amount of "Oh, come on, this is really silly" reactions--A Texas TV station went so far as to set up a blind test to prove that it made no difference--only it turned out that when people were given dried plums, most people thought they were sweet and tasty, while they disliked the prunes, and found them dry, bitter, etc. Only thing was that the dried plums and the prunes came out of the same box.
