I had to make a bunch of roses last minute for a cake I'm putting together tomorrow and want to know how I can harden the fondant quickly. Can I use a hairdryer on cool setting??
I would set a fan in front of them turned on high and leave it running all night. You could not run a blow dryer long enough to get the job done!
We used to harden dough ornaments in the oven when I was a kid. I don't know if fondant would respond the same way, but we used a very low setting on the oven, around 200 degrees I think and put the ornaments in on cookie sheets. again I am not sure it would translate to fondant, but maybe some of the experts will know.
The 200 degrees in the oven will definitely melt your fondant. Do you by any chance have a dehydrator? Those work fantastic but if not, the fan is your best bet, I think.
Made a cowboy hat... (last min cake) tried and tried and tried to make the ends bend up. I put it in the oven for a half an hour... worked like a charm. (on the 2nd attempt) I think I set the oven on warm, maybe a little higher. Watched it like a hawk. If you set it too high it will start bubbling.
I would just add tylose or gumpaste to it...will be dry over night if not sooner.I tried the oven thing once and it didn't turn out so well for me.
