I have two pans that I inherited from my Grandma. Just a 12" unmarked Lodge, and a 10" Lodge that I believe was bought new in the 1990's.
Anyway, both pans are visibly rough casted, but are better to cook with that the Griswold and no name pan that I bought that are smooth cast.
Bacon leave a sticky "goop" that is a beast to get out of the smooth pans, but real easy to get out of Grandma's pans.
I just wonder if it was what she used to season with, or the pans themselves. I've burnt the season out of the center of both Lodges doing steaks, but they seasoned right back up using the same practice I've used on all my pans.
