Thanks for the responses guys, I will try it next time and I may be surprised but like what Josh says, I get lots of heat, I can't cook a curry on full heat with my electric hob as it just burns/splats/evaporates everything far to quick, this is why I was also surprised when seeing the videos of Maliks because if I had left thing on the heat like I've seen them do, well, I would have some bad curries. But I guess it's a different kind of heat so I will be stinking the neighborhood out for my next curries outside.
