We've had "Korma Challow" at our local Afghan restaurant several times and absolutely love it. You choose either lamb or chicken and it's served with this delicious complex tomato sauce. I haven't found many recipes online but tried cooking it last night to no avail. I came close, but no cigar.
I threw in an onion, some garlic, a little ginger, and a can of tomatoes into the food processor and blended. Next, the mixture went into a saute pan where I added chicken broth, tomato paste, cumin, coriander powder, garam masala, butter, and a little brown sugar. I let this reduce and added seared pieces of chicken breast towards the end. I'm sure it would have benefited from more butter or "ghee". What am I missing (or doing wrong)?
