No. Because of the heat, it will melt. Believe me, I've tried it. You can chill it or keep it under room temp to dry it.
Try refrigerating it? be careful it doesn't sweat. An air conditioner might help better.
Yes. As long as you seal it in a ziploc or an airtight container, it will not dry out.
Fondant.
Marshmallow fondant can crack for several reasons, including incorrect moisture levels, overworking the fondant, or applying it when it's too cold. If the fondant is too dry, it may need a bit of water or shortening added to improve its elasticity. Additionally, ensure that the surface you're rolling it on is adequately dusted with cornstarch or powdered sugar to prevent sticking and tearing. Lastly, if the fondant is applied to a cake that is still warm or not properly cooled, it can lead to cracking as it sets.
fondant that is rolled
No. In fact, refrigeration will dry them out and make them rubbery even faster than leaving them in the cupboard.
Websites recommend at least a week for thorough drying. However, while it is best to use gum paste or royal icing which dries very hard for things like flowers or figures, if you have already made the fondant into something and you want it to dry quickly, then you can take a desk fan and have it blow onto the fondant for several hours. This will help it to dry faster. I found this information on the ehow.com website.
The fondant will crystallise
Can the fondant sealer be used instead of whipped fondant so it won't be very sweet or does the fondant have to rolled out thinner
so they don't dry out or get dehitraited
Tie a rope between two trees. Hang your clothes on that. The sun (if there is any sun) will dry them. That's how to use solar energy to dry clothes. (If it's windy, you'll get some help from wind power. Your clothes will be dry in no time!)
When you hang clothing out to dry, you are utilizing solar energy. The sun's heat and light help to evaporate the moisture from the clothes, allowing them to dry naturally.
