Hi CW!
Thank you very much- unfortunately the other half wasn't ready so was definitely over cooked so needed more base gravy as you mentioned, but didn't have any left! Haha.
You're right, I need to get the Kashmiri chilli powder and the marinades. I will put them on my shopping list! I'm presuming you wouldn't put the mince in the processor, just the spices/marinade?
That recipe is great though thank you! My colleagues have put an order in the next time we are on nights so I will have time to practise with this.
I'm going to need another Recipe book to put them all in.

Your curry looks good in the pan Jen, 
Shahi is a medium saucy finished dish, I would use a bit more base gravy
while cooking and also I would use Beef mince, just like
they do in most BIR and Take Away kitchens. (Bangladeshi owned)
