The gauntlet has been thrown down and I accept your challenge!
And.... I have failed! I looked online on Just Eat for a Turkish style place that sells both pizza and curries. The problem is even the ones that sell both don't seem to have the option to buy containers of curry sauce. I did find one, but when it arrived this is what I got. Not Indian style sauce, Chinese style. I tried it since I had it, and yeah dunking the cheesy pizza into the sauce was quite nice. But I really wanted a nice Indian curry sauce. Even the generic "curry sauce" would do, or preferably a Tikka masala or butter masala style sauce. I'll keep looking, might also try other food delivery sites to expand the search. We'll see what happens.
