Well, I have one cousin who does it that way at family gatherings, she brings little containers of food for her family.
So if you did it, we’d just assume you were a little neurotic or had bizarre food allergies. “It’s a shame about them... you know... they have problems” :~)
.....or the people you’re potlucking with can’t cook and you don’t want to risk ptomaine poisoning.
No, not little containers.
ALL the wimmin would bring that much. People who only brought one dish “just didn’t know any better.”
Bless their hearts. ;-)
