Frist we marinate our chicken. In a bowl, add the soy sauce, salt 1 tsp lemon zest, 1 tsp garlic paste, salt, black pepper, and turmeric powder. Mix well then add the chicken, allow to sit for about 10-15 minutes

After 15 minutes, add 2 tbsp of butter in a pan over medium heat, add the chicken pieces and allow each side to cook for about 5 minutes. Remove and set aside. Do not dispose off the remaining marinade. We'll use it in the sauce

In the pan, add the remaining 2 tbsp of butter, add in your onions, and stir for about 2 minutes untill they start to caramelize, add in green bell pepper, carrots, garlic and ginger and sauté. Cover and allow to cook stirring occasionally for 2-3 minutes. Add the pureed tomatoes,remaining lemon zest and some salt the cover and allow to cook 2 minutes.

Add in your chicken, if you opt for potatoes like me, this is when you put them in, then squeeze in the juice of half a lemon, add the remaining black pepper and turmeric powder, mix and let cook for a minute then add water. Let cook for 3-4minutes
