Interesting observation SS, and interesting reply Jeera.
I've had a lot of BIR curries that look like that, I know what SS is seeing.
On the other hand, we've seen comments/suggestions along the lines of start thin and boil off liquid, contrary to Jeera's comment. Which is right?
The other comment I would make from those pics of BIR dishes, is how oily they are. I usually do 3 tbsp of oil in a Madras, and end up thinking sometimes its too much. Seeing some of those pics, I don't think its enough.....
