How to freeze pineapple
Cut up the pineapple.
You can cut the pineapple in any way you like, really. First, cut off the tops and bottoms with a sharp knife, and then shave off the skins and cut out the core.
You can dice the pineapple, cut it into large circles, or cut it into smaller squares. You can even use a handy-dandy pineapple corer if you want to get fancy.
