Do you know when we were little, I mean did not know, our grandma used to take all the skin that was left from the chicken that had been used for soup and bake it in the oven. The skin which she called 'cracklins' were the best. I seemed to look for them. To this day, I know the skin is the best. At least tastes the best. Throw away the chicken and give me the skin, sure! Would be in ER tomorrow.
However, our grandma lived on farm and lived to be 91. What do you think the secret was? Ate eggs and bacon too. Now stuff we aren't supposed to eat. Had her own garden, chickens, cows, and worked very hard. Maybe that was it. She had to use her body more.
