Marinate Chicken Well: Allow at least 1-2 hours for flavors to penetrate. Cook Slowly: Simmer the sauce on low heat for a creamy, thick consistency. Use Fresh Spices: Freshly ground spices elevate the flavor dramatically. Balance Cream and Butter: Too much can make it overly rich; too little will reduce its signature taste. https://royalbiryanihouse.com/best-indian-butter-chicken-in-us/
