My dad liked to make big batches of popcorn with bacon grease in the skillet. This, plus a pack a day of Camels = living to the ripe age of 60.
My dad did the same thing only he smoked non filtered pall mall's and drank 3 16oz PBR's every day. He lived to be 80.
Awww...you brought back a fond (if not bizarre) memory of my mom who died when I was pretty young (not from lard, though!). She always bought lard and popped popcorn in it. And as a small kid, I always thought that tub of lard looked really tasty...so I tried it. I was wrong. But man, that popcorn was SO good! Never tried popping it in bacon grease. Sounds like a Saturday night experiment for me.
