I know this sounds a bit odd, but an Italian guy was in my shop tonight who comes from near Milan. He tried to tell me that in his province, the pizza margherita doesn't have basil. I didn't want to argue with him and happily made him a cheese pizza (or a margherita with no basil).
Personally I think he must just be a bit odd, because why order a margherita without basil when you can just order a cheese pizza?
Or is he right? Has anyone heard of this rabbit-hole Italian province where they make margheritas with no basil?
