Chicken Tikka Masala is a dish where chicken is marinated in yogurt and spices, grilled or seared until lightly charred, and then simmered in a creamy tomato sauce enriched with fragrant spices. Mary Berry’s version simplifies the process without compromising the deep flavors that make this dish so popular. It’s a combination of tender chicken pieces and a mildly spiced, creamy sauce that’s sure to please everyone at the table.
