Butter chicken tikka masala is a rich and indulgent version of the classic dish. The chicken is marinated in a mixture of yogurt, spices, and butter, which helps to tenderize the meat and infuse it with flavor. The sauce is made with a tomato and cream base, with an extra knob of butter added for richness. It's a decadent and comforting dish that will satisfy your cravings for a creamy and buttery curry.
