Hi, fondant doesn't dry here because of the humidity. I ordered some tylose powder. The directions said to add a certain ammount to fondant and then mix it in and let it sit over night before you use it. I followed the directions, then I wrapped it in plastic, and then put it in a tupperware, it sat overnight and then I went to use it today and it was hard as a rock. Is there anything I can do to save $6 worth of fondant? Should I microwave it? Add water? HELP.

I would try to gently microwave it. Be extra careful when you start to knead it. It can get hot spots that can stick to you and burn.
