For a luxurious twist on the classic butter chicken, try adding cashews to the recipe. The cashews add a creamy and nutty flavor to the dish, making it even more indulgent. The chicken is marinated in a blend of spices, yogurt, and lemon juice, then cooked in a rich tomato-based sauce with cashews. The result is a butter chicken that is rich, creamy, and full of flavor. Serve this delicious dish with rice or naan bread for a truly satisfying meal.
