I’ve never seen it or had it offered to me in an Italian place. Just olive oil with a little bit of herbs and maybe a pepper flake or two served on a plate with bread for a starter is the closest I’ve come, and that’s not very close.
Avalon Gardens Pizza used to serve it on the side to dunk your crust in.
I am sorry to report this great pizza place is closed after like 45 years in the obama economy
