Creating Indian Butter Chicken is straightforward if you follow these simple steps:

1. Marinate the Chicken: In a large bowl, combine the chicken, yogurt, lemon juice, garam masala, turmeric, cumin, and chili powder. Mix well, cover, and marinate for at least 30 minutes (up to overnight in the refrigerator).
2. Cook the Chicken: In a large skillet over medium-high heat, melt 2 tablespoons of butter. Add the marinated chicken and sauté until just cooked through, about 5-7 minutes. Remove the chicken and set aside.
3. Sauté the Aromatics: In the same skillet, melt the remaining 2 tablespoons of butter. Add the chopped onion and sauté until translucent, about 5 minutes. Add the garlic and ginger, cooking for an additional 1-2 minutes until fragrant.
4. Prepare the Sauce: Pour in the crushed tomatoes, stir, and let it simmer for about 10 minutes. Add salt to taste.
5. Add the Cream: Gradually stir in the heavy cream, mixing well to combine. Let the mixture simmer for another 5 minutes until it thickens slightly.
6. Combine Everything: Return the cooked chicken to the skillet, stirring to coat it in the sauce. Cook for another 5 minutes to warm through and meld the flavors.
7. Garnish and Serve: Remove from heat and garnish with chopped cilantro before serving.
