Chicken tikka masala

Chicken tikka masala is a curry in Indian cuisine that is made up of roasted marinated chicken (chicken tikka) in a curry sauce full of spices. Chicken tikka is made up of boneless pieces of chicken marinated in spices and yogurt, then roasted in an oven. The sauce is usually creamy and orange-coloured. Even though a sauce made of tomato and coriander is commonly used, there is no specific recipe for the sauce that everyone uses.
Chicken tikka masala is very popular in the United Kingdom, and it has been called a "true British national dish", as declared by British Minister Robin Cook. It is growing in popularity in the USA and Canada as well. Even though some consider it to have been originated by a Pakistani, the dish is unknown in most Pakistan. It can be found in restaurants in various parts of the world, due to its demand, not authenticity.
The oldest reference to chicken tikka masala is found in 1960s, where a Bangladeshi Chef, Ali Ahmad Aslam, created the dish in his restaurant in Glasgow, on request of a customer who was unhappy with the chicken tikka. Aslam is said to have invented chicken tikka masala by adding spices to a tin of tomato soup. Aslam died in 2022 at the age of 77.
Chef Anita Jaisinghani, a correspondent in the "Houston Chronicle", wrote that "the most likely story is that the modern version was created during the early ’70s by an enterprising Indian chef near London" who used Campbell's tomato soup. This is disputed by author Jo Monroe, who claims that this story was invented by the founder of a London restaurant "to entertain journalists".
Rahul Verma, a food critic who writes for "The Hindu" newspaper, claims: "It's basically a Punjabi dish not more than 40–50 years old and must be an accidental discovery which has had periodical improvisations."
