The fondant would not knead into a smooth ball.  It kept breaking and was a bit crumbly when I would turn it over, breaking apart.  I would add shortening when that happened.  I could not get it to knead without any breaks, but thought I'd give it a go and see how it does rolling out.

It rolled out beautifully into a 20" circle, smooth and lovely.

When I laid it on the cake, and draped it over the edge, that side broke off, immediately.

I have made MMF before and it was fine.  This time I tried L. Marek's after all of the wonderful reviews.

I have 5 lbs of it.  Any advice?  Can I fix it and use?

Thank you!

ADid you try microwaving it?

AUh oh- I see that I missed that step. Should I try it now to fix it ? Add more Wilton's ?

What marshmallows did you use?

AThe only genetic I could find- grocery store brand. I have jet puffed but did not use them . Even Walmart only carried jet puffed

Try just the microwave, I think you'll see a huge difference on how it handles.
