Jammin'

While I don't actively enjoy jam, jelly, or marmalade, I do find it interesting to know the difference...plus, all of them oddly have songs about them:
Jam: made from fruit...so that's why there are little chunks in it.  Pump it up!
Jelly: Made from the fruit juice...Good even without peanut butter for someone like me who's allergic. Jellyhead!
Marmalade: Made with the peel/pulp...The best song of all!  Creole Lady Marmalade.
