Does pineapple belong on pizza?
There are simpler options that do not require a trained chef to perform (i.e. keeping a pizza dry from pineapple's added moisture).
If this is an issue, dried pineapple is an option.
Pineapple can be added after the pizza is done (because it is edible raw) to not let the juices seep in for a soggy crust.
People can also squeeze out the juices of canned pineapple before apply it to pizza too if they are worried about the juice.
