A lot of the flavor comes from cooking the bones and carcass down in the water. You'll be surprised how much flavor comes from just that! However, the beauty of this chicken soup is that you can flavor and season it however you like. In terms of spices, I used some smoked paprika, turmeric, thyme, salt and pepper. As for herbs, I just used fresh parsley because to me and the BF, that's all ya really need! However, feel free to change it up a bit and use whatever spice and/or herb combination you want!
