I made Marshmallow Fondant about 3 months ago.  I wrapped it in plastic wrap and placed it in a zip lock bag.  Will it still be good or should I make new fondant?

Thanks!

ADo the old sniff and taste test lol. In all seriousness though, I doubt anything has spoiled. The workability tends to go before the fondant actually spoils

AYeah, to me, if its still workable, its still good!
