Glaswegian who 'invented' chicken tikka masala dies. BBC.

Ali Ahmed Aslam is said to have come up with the dish in the 1970s when a customer asked if there was a way of making his chicken tikka less dry.

His solution was to add a creamy tomato sauce, in some versions of the story a can of tomato soup.

Known to friends and customers as "Mr Ali" he was born in Pakistan but moved with his family to Glasgow as a young boy before opening Shish Mahal in Glasgow's west end in 1964.

Note: BBC article has his name as "Ali Ahmed Aslam" but called "Mr Ali" and links to the restaurant's fb page post about Mr Ali passing away.
