It's a kind of combination that sounds odd, but which turns out pretty good once you try.
There's a lot of variety of pizzas out there, some even weirder than the other and some really downright disgusting.. at least, I don't like it if you do, go ahead and eat it... Like anchovies for example. But as soon as pineapple is mentioned, people act like silly fools....
And I wonder why people rage about it lately because the recipe is not even knew... I ate my first pizza with pineapple somewhere in the1990s I think, and even then the recipe was old already, and nobody complained... Oh well...
