Is it normal to eat ketchup with pizza?
Depends.It depends
Sure—ketchup on pizza is a normal taste preference, even if it’s a divisive one. Some people love the sweet-tangy boost; others think pizza already has enough sauce.
There’s no pizza police. People add ketchup because they like the extra sweetness and tang, or simply because that’s how they grew up eating it.
Some people will raise an eyebrow, especially if they’re firmly in the “pizza needs no help” camp. But food preferences are personal, and ketchup on pizza is harmless—enjoy your slice your way.
