Chicken tikka masala is a popular British dish that has its roots in Indian cuisine. It consists of marinated and grilled chicken pieces cooked in a creamy tomato-based sauce. The sauce is made with a blend of spices, including cumin, coriander, turmeric, and garam masala, which gives it a rich and aromatic flavor. Chicken tikka masala is typically served with rice or naan bread. It is a favorite among Brits and is often considered the national dish of the United Kingdom.
