As far as I can see, pastes are now being used as a matter of conveinience, but more importantly, as a matter of speed.
If, say you're average takeaway can only put out 300 curries on a busy night by preparing curries in the "old" way, but by adding a spoonfull of this or that they can then get out 500 curries, well, it's a simple matter of economics. They are well aware that with other added ingredients, it is still a tasty option for the "average" punter, who is either too ignorant/lazy to cook his/her own, or who doesn't have the inclination to do so.
If the premises are paying HUGE rents, and they can increase turnover in this way, then it is an easy way out, and the newer generations have accepted the taste and are happy to pay for it.
Nostalgia aside, the curry's of the 70's and 80's WERE so much tastier........END OF STORY. It is isn't just fond memories, they were gorgeous.
As for pastes in tikka/seekh...well i don't know. I rememeber having seekh kebabs down Wilmslow Rd in the 80's and they tasted absolutely divine. However, at the local curry houses in Manchester's outskirts, they were obviously made with pastes. (I didn't know this at the time, but since discovering CR0, I do know the difference in taste now)
Seeing as I left UK in '96, I cannot comment on recent takeaway/restaurant curries, apart from trips back home , where I have sampled curries that are OK, to others that were sublime. Even the OK ones knocked the spots off you're average OZ/NZ piss weak watery shite.
