Does pineapple belong on pizza?
Invented in Ontario in 1962, banned by a president's joke in 2017, loved and hated in roughly equal numbers. The Judge rules. Below: both sides as they'd actually put it, then the ruling The Judge gives when two people bring this one into a Settle It room.
Both sides
Sweet, salty, acidic, hot. Pineapple and ham is the same logic as prosciutto and melon, and nobody screams about that.
Fruit does not go on a savory pie. Pizza is Italian; pineapple pizza is Canadian; that is the whole argument.
The Judge's ruling
Ruling: Leo is right about the facts and wrong about the conclusion. Hawaiian pizza was invented in 1962 by Sam Panopoulos in Chatham, Ontario, so it is Canadian, not Italian. But 'not traditional' is not a ruling, it is a history lesson. Nina's flavor argument is sound: the sweet-and-salty pairing is everywhere in cooking, and the acidity cuts the fat. The court finds no principle by which pineapple is banned but barbecue chicken is allowed.
Sentence: Pineapple stays on Nina's half. Leo never has to eat it, and never gets to say 'Italy' again unless he is buying tickets.
