Hi Folks,
I also made this sauce earlier this week and yes it was even darker than this.
I'm not sure, but I think I salted twice by mistake.

I left it sitting for a day defore making the finished curry.
I didn't spice the finished dish much more as I wanted to taste it as is (this is not normal for me!!)
I fried some chicken pieces removed them and then fried an onion slowly for ages so it was caremalised. Added some base sauce (warm) bit by bit and then put back in the chicken with some fresh chopped green chillies and a sliced tomato. Heated everything thoroughly before adding chopped coriander prior to serving.
Served on Cory Anders left over perfect pilau rice.
Superb! ;D
Should have taken a few pics really!
