I often buy full chickens in supermarkets and boil it. I noticed that its outermost breast skin part (only skin and only that part where you would expect nipples) tastes like soap. At first I thought that maybe I didn't clean the dish-washing liquid from the fork completely or something but then I realized that this happens with ALL chickens I bought... They were from different sources, of different sizes and complexity. Does any body know the reason? Thanks
