1To make the green chutney, combine 2 cups of fresh cilantro leaves, 3 cloves of garlic, 1 teaspoon of toasted cumin seeds, 1 teaspoon of kosher salt, a 1-inch knob of peeled ginger, and three green chilies (like Thai chilis) in a blender.
2Add a splash of cold water to the blender.
3Blend on medium speed, gradually increasing to high, adding small splashes of water if needed, until smooth.
4Transfer the green chutney to a serving bowl.
5Cut 1.5 pounds of boneless, skinless chicken thighs into 1-inch cubes.
6Combine the cubed chicken with 2 teaspoons of kosher salt, 1 tablespoon of lemon juice, 1 teaspoon of fresh grated ginger, and one medium-sized grated garlic clove.
7Mix thoroughly until the chicken is evenly coated.
8Refrigerate the chicken for at least 30 minutes or up to 2 hours for the first marinade.
9To thicken 1 cup of whole milk yogurt, place it in a clean tea towel, gather the sides to form a sack, and tie it with kitchen twine.
10Hang the yogurt for 2 to 3 hours or overnight to allow the whey to drip out, resulting in a thicker hung yogurt.
11Alternatively, if not hanging the yogurt, add 1.5 to 3 teaspoons of bassan flour to thicken it.
12For the second marinade, combine the hung or thickened yogurt with 2.5 teaspoons of Kashmir chili, 1 teaspoon of turmeric powder, 2 teaspoons of lemon juice, 1 teaspoon of ground cumin, 1 teaspoon of methi or fenugreek leaves, 1 teaspoon of coriander powder, 1 tablespoon of garam masala, 2 teaspoons of fine sea salt, a 2-inch knob of fresh grated ginger, 2 cloves of grated garlic, and 1 teaspoon of mustard oil (optional).
13Whisk the marinade ingredients together until thoroughly combined and thick.
14Add the chicken from the first marinade to the second marinade and massage the mixture into the chicken until fully coated.
15Wrap the marinated chicken in plastic wrap and refrigerate for at least 2-3 hours or ideally overnight.
16Skewer the marinated chicken pieces onto metal skewers.
17Grill or broil the skewered chicken for 2 to 3 minutes per side, flipping to achieve even char and cooking on all sides.
18Heat a large saucier, pot, or deep pan over medium heat and add 2 tablespoons of ghee.
19Once the ghee is fully melted and hot, add one small diced yellow onion, a 1.5-inch knob of finely chopped ginger, and seven finely chopped garlic cloves.
20Add a touch of salt to taste and sauté, stirring frequently, for about 3 to 4 minutes until the vegetables are softened.
21Add 2 to 3 teaspoons of granulated sugar, 2 teaspoons of coriander powder, half a teaspoon of cumin powder, half a teaspoon of turmeric powder, 1 teaspoon of Kashmir chili, 1 teaspoon of garam masala, and a hefty pinch of salt.
22Stir and continue to sauté for about 30 to 60 seconds over medium heat until the spices are fragrant and slightly darkened.
23Stir in 1 tablespoon of tomato paste and sauté for one to two minutes until it darkens slightly.
24Add a 14-ounce can of crushed tomatoes, followed by 1 and 1/4 cup of water and 1 tablespoon of methi (fenugreek leaves).
25Increase the heat to medium, bring to a boil, then reduce to low and simmer.
26Optionally, create a spice bag by wrapping one cinnamon stick, six cardamom pods, and five whole cloves in a cheesecloth and tying it with kitchen twine.
27Add the spice bag (if using) to the simmering curry sauce and let it simmer for about 10 to 15 minutes.
28Remove the spice bag and carefully transfer the curry sauce to a blender.
29Blend the sauce on high speed until it is as smooth as possible.
30Pour the blended sauce back into the pot or pan.
31Bring the sauce back to a light simmer over low heat.
32If the sauce is too thick, add about 0.5 cup of water to reach desired consistency.
33Melt 2 tablespoons of ghee in a bowl.
34Place the bowl of melted ghee into the curry pot.
35Carefully place a hot piece of oak lump charcoal into the ghee to smoke it, then immediately cover the pot.
36Let the ghee smoke for about 1 to 2 minutes or until the smoking stops, then remove the charcoal.
37Strain the smoked ghee through a fine mesh strainer into the curry and stir it in.
38Add 0.5 cup of heavy whipping cream to the curry and stir.
39Bring the curry to a boil over medium-high heat, then reduce to low and simmer for about a minute.
40Add the grilled chicken to the curry and simmer for 5 more minutes to combine flavors and ensure the chicken is cooked through.
41Remove the pot from the heat and add 1 to 2 tablespoons of cold unsalted butter, stirring continuously until the butter emulsifies into the sauce, making it velvety and creamy.
42Taste the butter chicken and add more salt if needed.
43Ladle the butter chicken into bowls, serving with fresh chicken pieces.
