Combine the cubed chicken breasts with all the ingredients needed for the marinade.
4 Chicken breasts, ¼ cup Plain greek yogurt , 2 tbsp Lemon juice , 1 tbsp Garlic paste , 1 tbsp Ginger paste, 1 tsp Chaat masala , ½ tsp Garam masala, 1 tsp Kashmiri Chilli powder , 1 tsp Paprika
Bring a large skillet to medium-high heat. Saute the marinated chicken with a tablespoon of butter, until the chicken is cooked through and lightly browned. Remove the chicken from the skillet and set aside.
1 tbsp Salted butter, 1 tbsp Garlic paste, 1 tbsp Ginger paste , 15 Cashews, 1 Cinnamon stick , 2 pods Green cardamon
Add the ground spices to the skillet, and toast. Add the tomato passata to the skillet, and let it cook through until the water has evaporated, and it has thickened.
1 tsp Kashmiri chilli powder , 1 tsp Garam masala, 1 cup Tomato passata, 2 tbsp Sugar, Sea salt, 1 cup Water
Once the passata mixture has thickened, remove the visibly large spices like cardamon pods and cinnamon sticks, and put the sauce into a blender. Add half of the water, and blend until smooth.
Return the mixture back to the skillet, and add the remaining water. Add the sugar and salt, as well as the chicken. Finish with heavy whipping cream, and dried fenugreek.
