I made this chocolate marshmallow fondant a while ago I though it stayed good forever, well I'm trying to roll it out or knead it, and its a crumbly mess. Help Please!!!

Add some shortening and knead it really well. You can also heat it in the microwave for 5 seconds and soften it a little.

How long does it stay fresh....Or last

Ditto on the microwave..........don't do it too long or else you'll burn your hands.

I made some over a month ago, and it's still pliable.

I put it in the microwave for 30 sec intervals ( maybe it was to long I'll try 5 sec intervals ) because it was still crummy I added some Crisco and tried kneading but still no avail.

The recipe called for 1 tsp. oil or extract I used the extract does that make a difference? I used the Choc-MMF recipe I found on this site.

I use Rhonda's Ultimate choc fondant recipe.

OH thanks so much I'll try that recipe next time, did you find it on this site?
I've been looking around and can't see it. DuH. Sorry.
What is the link to the recipe?

The recipe is here on cc, go to recipes and type in chocolate mmf. The recipe is Rhonda's Ultimate chocolate mmf.

Hooray!!! I can't wait to try out this recipe, and decorate some cake!!!
THANK YOU SO MUCH FOR ALL YOUR ADVISE AND HELP !!!
YOUR AWESOME!!
