My late grandmother called hers a spider.
The thing was freaking huge.
Good thing grandma was built like a tall tank.
And nobody else touched it.
She cared for it, seasoned it, had it for decades.
I think that thing could have stopped a mortar.
A spider skillet has three legs, which mine doesn’t. At least mine’s from back when the manufacturers would grind the cooking surface of the pan smooth, which they all seem to have quit doing quite a few years ago.
