My mom did not smoke but she sure used lard. She died 3 months before her 103rd birthday. We miss her.
My Mother also cooked with lard. She also would put a teaspoon full of meat grease on her biscuits. She really knew how to cook.
I guess in the 60s she began to read that vegetable oils were more healthy and changed over to peanut oil, Crisco or Wesson oil. I don’t guess the lard hurt too much as she lived to 86 and Daddy to 90.
