Pope Leo XIV has revealed his favorite toppings for a hot dog during an informal exchange with worshippers outside the Vatican, in a moment that quickly drew widespread attention on social media, according to the British newspaper Daily Mail.

During the conversation, the Pope said he prefers his hot dogs with mustard and ketchup, after being jokingly told by one of those present that he had “eaten more hot dogs than any pope in history,” referencing his origins from Chicago in the United States.

He initially replied jokingly, “Just mustard,” before quickly correcting himself: “Mustard and ketchup.”
