Does south asian and carribean/african food suited to the British palate count as "british food"?

Yep, a matter of opinion. I am south asian, and obviously my grandparents came in the late 60s/Early 70s from pakistan and bangladesh or a better life. Anyway, thats not the point. For example, tikka masala is an indian/pakistani dish. Chicken tikka masala, however, is the same concept with less spice, smothered in a creamy sauce to suit the British palate. When afro-carribeans came in the late 50s/early 60s, and the Notting Hill carnival became a think foods like jollof rice and jerk chicken in most cases were altered. Does this make them British food along with also being from their own countries respectively? So then British food isn't just the stereotypical fish and chips, but also a large cultural melting pot?
