I tried to make candy for the first time,not good. The candy did not set up in the molds,it is tacky when I touch it.I have left it over night at room temp. My question is how do I get it out of the molds ? What do you think I did wrong? I heated to 240,let it cool to about 180,then I stirred it about 5min. poured into the molds. Any suggestions.
