I made MMF for the first time today thinking I would need it soon. I won't be needing to use it for about 2 weeks, I have it double wrapped and in a ziploc. Should I store it in the refrigerator or on the counter?
On the counter. It will be fine. It may seem dry and stiff when you go to use it but don't add anything to it. If you just work with it and knead it, it will become pliable and workable.
I would go further and put in something airtight. If it dries on the surface and seems 'crusty' be sure to remove the hard bits. They will not knead into the smooth fondant and you will have little hard bits throughout.
Thank you. I placed it in an airtight container and left it on the counter.
I have not tried it with MMF, but with regular fondant I wrap it about three times and put it in a ziplock freezer bag and squeeze out all the air and freeze it. When I need it I take it out the night before and let it thaw on the counter just as I put it in the freezer. It seems to have no ill effect on it. I make my own ffondant.
I have always made my MMF a few days ahead, wrapped it tightly and stored in the fridge, when I take it out I put it in the microwave for 10 seconds and it is ready to go. I have kept it this way for weeks, and it alway seems the same just perfect.
