I have not had pork hocks or feet in ages. My mother would occasionally make them. At that time some of them still had some hair on the skin. She would first run them over a flame to burn off any hair. If she missed,(things happen) then I remember getting that 5 o'clock shadow feeling on my tongue.
Yours look like the smoked variety. They should be pretty much hair free. Have you ever encountered what I mentioned above?
Yes! My mom would use the flame on the stove to burn them off. Every once in a while I get one with a few hairs still attached, even smoked.
