I watched them keep those pans black and slick and perfect for decades.
Cites durability, maintenance, seasoning durability
oil and heat, and it lasts forever. My diner cooks wouldn't have touched a coated pan.
Scrub it down to bare metal with a good scour and season it fresh. It's near indestructible.
Skip the oil and it rusts. Do it and it lasts forever.
A carbon steel pan kept right doesn't wear out. It improves year after year, decade after decade, blacker and slicker all the while.
My diner cooked on the same pans for as long as I worked there and longer.
They truly do not wear out.
gimmick, no shine, just plain metal that gets better the harder you use it and the longer you keep it.
