how do i firm up marshmallow fondant? i have run out of tylose and I won't have any until it's too late. I have gum tex, can I use that to help the fondant not be so "squishy"? Thank you for your help!

are you wanting to make figures or something with the fondant as to why you want to firm it up?

I am actually wondering about this too, I love MMF, but for me it seems to droop a bit after I get it onto a cake. Meaning, even if I cut right close to the cake, when I come back to it later to decorate, I have to cut the edge off again because it is longer than the side of the cake. I am afraid if I knead more PS into it, it will crack.

eccl1-12,

I'm not sure how to help you with that I have never had that happen....maybe it does need more ps????
