It has a wonderful sweet and sour flavor, the tangy tomato sauce, paired with the sweet, tart pineapple, and then swathed in the nutty, mellow, but slightly tart flavor, of the mozzarella cheese. It’s quite different than most pizza toppings, which tend to be completely savory. Although it lends a sweet flavor, along with a tart flavor, it is definitely not a “dessert” kind of flavor, if you are worried about that.
A lot of people who like pineapple, do not like it on pizza. I am one of those people who like pineapple by itself, and on pizza, and in most other ways it can be served. Grilled fresh pineapple is one of the most delicious things in the world.
You will probably love it or hate it. Pineapple on pizza is one of those things that tends not to be in anyone’s middle ground.
