Caramel nightmare

[piggeh]

I was bored today so whilst I thought I would make some caramel shortbread out of boredom. I couldnt find the scales so took rough guesses on most of the stuff. The shortbread came out ok, but the caramel I've left to set for an hour now and it's still very runny.

How long do you have to leave it for it to set? The recipe was for quite a soft caramel and was just brown sugar, marg, and condensed milk. How long do you usually have to leave caramel for it to set? And is there a way to make it thicker in case I added too much condensed milk/not enough sugar?

Have you put it in the fridge? That might help.

Arrr, I didnt put it in the fridge for long enough. When I left it overnight it settled properly and was actually bloody gorgeous. But I had left it for a couple of hours in the fridge after cooking and it was still really runny, and the recipe didnt say how long it takes to thicken up! :/
