Step 1Marinate the chicken: Bring the chicken and the rest of the marinade ingredients together in a large bowl.

Drizzle a teaspoon of oil to the pan.Working in batches, remove chicken from the marinade and grill them on the pan for 3 to 5 minutes on each side, until the chicken is cooked through (clear juice runs out of it when you cut into it). Do not crowd the pan.Once cooked, transfer the chicken into a separate dish. Cover and set aside for later.Step 4Start making the sauce: Melt 1 1/2 tablespoons of the butter in a medium sized Dutch oven or a skillet on medium low heat. As soon as the butter melts, add the ginger garlic paste followed by sugar. Sauté for 1 to 2 minutes.Stir in the tomato and cook for 8 to 10 minutes on medium high heat, until all the extra liquid is cooked off.

Add the water to the paste and stir to make a smooth sauce.As the sauce begins to boil, add the grilled chicken and heavy cream. Stir well. Cover the pan and simmer for 5 minutes.Step 7Rest the butter chicken: Turn off the heat and uncover the pan. Stir in the remaining 1/2 tablespoon butter and the kasuri methi. Cover again, and let the dish rest for 8 to 10 minutes so the flavor of kasuri methi can marry into the butter chicken.Step 8Serve: Serve the butter with a side of steamed basmati rice, roti, or naan.
