I have recently started making toffee and I LOVE it! However, I have noticed that the chocolate stays soft at room temp, and I wanted to package it to use as gifts at the holidays. Can anyone suggest how I can make the chocolate solidify so I don't have this problem? I have been just using Nestle chocolate chips that I put on top of the hot toffee after pouring on a sheet pan. I let it sit for a couple of minutes and then spread it out with my offset spatula, and then I chill in the fridge for a couple of hours before breaking up.
