Hi all ! I am very new here but I have to say I have learne a tremedous amount of info. The photos on this site are wonderful. I do have a few questions about MMF. I made my first batch yesterday. I have never used fondant of any time only buttercream and a couple of times royal icing (hate it
I think it really depends on your climate. For me, it takes way longer in the hot, humid months than it does in the dead of winter when it's so dry. I'm making MMF flowers for the top of my daughter's 11th birthday cake (it's Thursday!) and I'm keeping my fingers crossed that they set up in time. We're suppose to have nice, dry weather all week, so chances are everything will be fine.
OOOops! I just realized you asked how long does it keep! It should be good for a long time. After it hardens, probably indefinitely. I would keep it covered to protect it from dust, though.
Thanks so much for your answer. I let it set and dry. So now gonna wrap in tissue paper just to keep the dust off. Good luck with your cake.
