I did a trial run on MMF tonight, and for once, I think I got someting right on the first try! I was wondering how long MMF stays good. I wrapped it in saran, and put it in an airtight container in the fridge. I wasn't planning on using this for my cake next week, since it was a trial run, but will it keep that long?

Yes, that is the beauty of MMF! It will keep well for 2 weeks in the fridge. I coat it with crisco, wrap in saran and put it in a ziplock bag (push as much air out as possible!

You're a mind reader! I was just looking at Rhonda's MMF a minute ago and was wondering how long it kept!

If it's too firm when you finally use it, don't knock yourself out trying to knead it soft...microwave! and it'll be perfectly pliable.

How do you guys keep it from getting too soft? I can use mine but it gets so soft it wants to tear but I worry if I add more sug that it won't be stretchy enough or will get too sticky. Tia.
(Ps this is why I love satin ice but can't afford it for gift cakes.)

I agree - Jet puffed marshmallows - the only way to go!

I store mine in the pantry for MONTHS! Still as good as new. I just zap it on 5 second increments to soften back up.

i was wondering why the recipes say don't use jet puffed when that's what i used before i read that and haven't had any problems, anyone else know what the recipe says don't use jet puffed?

I'm not sure, it may have just been someone's personal preference.

I used Wal-Mart's brand (which was the suggested choice) quite a few times, but it was sooo sweet, I always added grounded up salt, I don't need any when using Jet Puffed...also I had problems with pockmarks and bubbles.
It was inconsistent, which is the main complaint MMF usually gets.

So abra526 since this is your first time making MMF and you seemed to really like it, I have to ask which recipe you used? I want to try making it but there are 8 zillion different recipes on here and I have no idea which one I should try.

I was in the same boat, not knowing which recipe to use. A friend of mine sent me one that she got from cakejournal.com. If you search for marshmallow fondant, it takes you to a page with a sugar cookie recipe, then down a little bit there is a link to "how to make marshmallow fondant", and that's the one! Good luck!
