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 dry Chicken Tikka.
