I made some caramel for turtles and candy...they turned out delicious but I wrapped the leftover caramel. Now it has harden and became crumbly. I don't know why though. I thought it might be that I didn't wrapped it good enough but then again the turtles wasn't wrapped and the caramel is still chewy. any ideas??

I have the same thing happen to me and I don't know why either. Half of the caramel that I use for turtles, or apples turns out fine but towards the end of what I'm making or what I have left over gets grainy and opaque looking. If I reheat it and add a little more cream sometimes it goes back to normal but then again towards the end of what I'm doing it does it again. Glad I'm not the only one having this issue.

does anyone have any suggestions??

You can heat it up in the microwave & keep adding evaporated milk (regular milk could work too) til it gets the consistancy you want.
