Its all about preference I suppose, the thickness between us is probably not too different (just describing it is hard!)
Probably a good way to think about it is the difference between a takeaway madras in a foil tray and a restaurant version in the small balti dish, the takeaway has lots of sauce and is quite runny wheras the restaurant is a bit thicker and more intense - thats where I would say mine is once I see those craters.
The slow bubbling "lava" craters are really just telling me that the base in the sauce has been fried due to the excessive oil and has caramalised/sweetened - Im getting hungry now!!
