Hi Liz, I’ make mmf all the time (only thing I use) and I only use marshmallows and icing sugar. I guess I’m just used to this recipe of mine as it rolls out really well, can use it to make gumpaste/figures/flowers and use shortening to ensure there’s never any elephant skin so just wondering what are the benefits of adding the store bought fondant? I do have to let mine rest though, haven’t actually tried using it straight away! Thanks for posting here, I have watched your YouTube vids many times :D
