Phil,
I have seen some posts that question the use of curry powder (undefined/questionable ratios) of spices/powders to then be added as a 'Spice mix' with the spices in the curry powder.
I have made a few versions of Chicken Tikka from this site many times and my wife has decided on her favourite (who am I to disagree, it is not sensible

)
I am therefore somewhat surprised to see you recommending a 3rd party ingredient, Laziza tandoori spice mix paste, without the usual interrogation of what is actually in it.
I have used Laziza shami kebab masala before, it was very good.. but I have not made a single beef/chicken or lamb burger/kebab since a very close friend of my daughter and ours died of Hodgkin Lymphoma at the end of 2017. I have some packets of it in my cupboard that are now out-of-date but unopened, they will probably just have less 'flavour' and be less aromatic if I was to use them. Right now, I still do not have the will to make them as they were a favourite and I am not ready yet.
