I like my pizza spicy and pineapple is generally inconsistent in providing both sour and sweet taste which messes up the spiciness of the pizza and the sauce hence I don't like it
look im not totally against it but when u buy pizza the pineapple pieces are too big and overpowering, they need to be thinner and smaller to provide the perfect amount of sweetness
The thing is the pineapple loses a lot of its sweetness when it warms up so the cheese blends well with it. Raw pineapple on pizza is just as disgusting as any other raw fruit on pizza.
