Yellow Fingers, The chef spoon is probably about 4 level tbls. The colour was a red/brown consistency - it leaves a trace of tumeric coloured oil on the plate, but by no means floods the plate. I used only 1 tbl of oil in my last 2 final dishes and the texture came out much better - with no difference in the final taste.
It might be tandoori marinage but it looked smoooth and watery - maybe it was watery ketchup ?? No idea realy - this is bloody annoying

I'd love to know what this white stuff was also.
I don't think the tandoori marinade is relevent to the Tikka dish in this case though - in my area, chiken tikka is often used as a straight replacement in any dish. I tend to get this as sometimes I find some BIR pre cooked standard chicken to taste *off* - i never get this off taste with BIR Tikka.
Home made pre cooked is different matter though - In fact, I prefer it.
