The invention of one of the most popular chicken curry of India, butter chicken is a creamy and luscious affair. Kundan Lal Gujral has been credited for the invention this dish. He worked at a Peshawar restaurant in the Pre-Partition era. The owner of the restaurant passed on the legacy to Kundal Lal and he established Moti Mahal. He moved to Old Delhi after Partition and devised this concoction. He found a method of keeping tandoori chicken soft and creamy with the help of tomato and onion gravy. That's how the iconic dish came into being. Butter chicken is prepared with marinated chicken that's first grilled and then served in a rich gravy, made with tomato, butter and a special spice blend as a base.Unlike most Indian curries, where the preparation of the base starts with a blend of onion and ginger-garlic paste cooked in oil, butter chicken uses tomato as a base and is cooked in butter, giving it a slightly sweet flavour. Cashews and almonds add to the sweetness and nuttiness of the dish.
