cooking feet..... i have heard people use chicken feet for stock, and flavoring, my question is how do you clean them?, do you soak them in anything special?, do you skin them?, if so, how? please let me know. I.D.ing the innards...... does anyone have pics of the chicken but open and, more specifically, have the innards identified, i know some of you computer guru's can do something to tag parts of photo's..... right?... or links would be helpful.
