Even though this curry has global status, who doesn’t love this dish, it is technically not a traditional Indian curry.  It was created by Indian chefs living in England, using the spices and techniques of traditional Indian cooking, but with certain adaptations for the palette of their new clients.  Be this as it may, there is reason why everyone loves it, the sauce is rich and flavourful and because the chicken is cooked separately the meat has a wonderful smokey flavour.
