If using a fresh pineapple, cut it up and freeze the chunks overnight. Or you can purchase pre-cut pineapple, frozen pineapple chunks, or freeze canned pineapple chunks in an ice cube tray. (Many other fruits would also work well with this recipe!)
Combine the frozen pineapple, milk, and honey in a high speed blender (like Vitamix or Blendtec, or try a food processor) until it reaches a smooth, thick frozen sorbet consistency. You may need to blend it in two batches if your appliance is struggling.
For an authentic presentation, transfer the pineapple whip to a large plastic bag and cut off one corner to create a large piping bag. Pipe the mixture into 4-6 dishes and serve immediately.
Notes
Pour leftovers into an ice cube tray and freeze to use in smoothies. Or make popsicles!
