Chicken in peanut butter-tomato sauce

A recipe from sub-Saharan Africa. I have found this recipe on websites describing food and travel in Congo, Ethiopia, Nigeria, and Senegal, and it is listed as one of the national dishes of Congo.
The question always arises whether these flavors in my recipes are also authentic and specific to the area. The answer to this question is probably both yes and no. There are some nuances in the local restaurants that give a completely different and unique variation. The spices are also grown in different regions from those available in Estonia and taste different. At the same time, I have not met two chefs who could prepare very similar food following the same recipe.
In my recipes, I have used as real recipe sources as possible and tried to find local publications from which to find inspiration. I have also used as authentic spices as possible. So yes, these recipes reflect local tastes as good as possible and no, they have nuances that make this food unique among all foods made according to the same recipe.
