Totally agree Frank its well worth the effort
Ive made this twice, first time it caught on the bottom and half the meat was ruined

the second time I put a heavy frying pan under the pot as he suggested

worked a treat.
Must admit i have taken the easy approach the last couple of times (i don't make it very often)
but its a good recipe if you have to cook for a few friends

I should try it again.. anyone fancy a Bir-yani
