what is MMF???
Well first of all, let me welcome you to CakeCentral... second, no question is stupid ... and MMF is marshmallow fondant .. it's cheap to make, easy to use and taste much better than some bought fondants
That's not a stupid question! MMF is Marshmallow Fondant, the recipe is on this site at: http://www.cakecentral.com/cake_recipe-1949-0-Marshmallow-Fondant-MMF.html and a tutorial here: http://www.cakecentral.com/article47-How-to-Make-and-Decorate-with-Marshmallow-Fondant-MMF.html
oops, I guess I'm a little slow!
