I just tried MMF for the first time this week and I think it's great!!
I was using the "Virgin Ice'" brand from a local cake bakery and the taste of it was not too bad. So compared to that, I would say the MMF is definitely better tasting, but not extremely noticable. Although the best part of MMF, to me, is that you can add any flavour you want to it!!
It is most certainly cheaper, and you can get it paper thin for roses. I also read on this forum that you can roll it out to 1/8th inch thickness, whereas with the store bought, I rolled it out to 1/4 inch which meant using more.
I've definitely been sold on MMF!! Thanks to everyone on this forum for all the great advice and tips.
My next attempt is to put it on cookies!
