So I'm making a chicken curry in my slow cooker and it's still really watery. It doesn't seem to be getting any thicker 
I put it on high at about 4.30 and on the recipe it says 3-4 hours on this heat should be right.
What can I do to make it thicker? I'm to add coconut milk towards the end but I don't know if this would make it any better.
Please help!
