Hi all, sorry to jump in to this thread uninvited

have had a good read here and also agree a stock would lift a dish to a different level, but believe it would be to costly for a BIR to to produce a separate stock for Balti dishes.
This leaves me with the understanding that a Yakhini stock or Pakistani chicken stock must be made using chicken wings.
Then removing the chicken and discarding the bones leaving the stock to be drained for adding to base, a Pakistani veggie stock can be added to base for a veg gravy.
I can confirm the butchers next to my indian TA sell all there chicken wings to them, but they are not on the menu!! So i would assume it's got to be a form of chicken stock they are producing here using wings.
