Fact: at least three Indian dishes well known in the UK and elsewhere are in fact British and not Indian at all.

Balti was invented somewhere in the West Midlands, and literally means bucket. While the principle is Indian, the specifics are more British than Fish and Chips.

Bombay Mix, aside from being the snackfood equivalent of mild, are also a UK invention, having been dreamt up by a food magnate named Noon. Almost certainly manufactured by sweeping out the machines that make Pot Noodles.

Chicken Tikka Masala: The story is this. A Brit went into an Indian restaurant and ordered Chicken Tikka. When it arrived, he declared 'Where's the sauce?' The waiter, in a fluster, took it back to the kitchen, but all that could be found was a tin of Heinz Cream of Tomato soup. This was duly heated up and used as garnish, the Brit went away satisfied, and Chicken Tikka Masala was born.
