Chicken tikka masala (1970s)
Glasgow chefs took Indian chicken tikka and added a creamy tomato sauce to suit British palates. The dish spread across the UK and is now often called Britain's national dish.
Indian restaurants across Britain added the dish, and it became a menu staple nationwide.
Indian fusion food moved from immigrant niche to mainstream, opening the door for later curry-based inventions.
Curry & Crust's butter-chicken pizza follows the same pattern — Indian flavors adapted to a staple of the host cuisine to widen their audience.
