Preheat your oven to 200°F or 100°C.
Cut off the bottom and top parts of the pineapple. Also, remove the rind and seeds.
Cut the pineapple into thin slices. The best way to do this is by using a mandolin slicer. If you don't have one, use a sharp knife instead.
Dry the slices with a paper towel to remove excess moisture in the fruit.
Line a baking tray with parchment paper and place the pineapple slices onto the paper. Make sure they don't touch or overlap.
Bake or dry the pineapple flowers for 40 minutes, then turn them.
Bake again for 35 minutes, and your slices should be completely dry. If they still feel juicy, pop them back in for another 15 to 20 minutes.
Optionally, put the warm and dried pineapple slices into muffin forms to shape them.
Store your dried and edible garnish in an airtight container.
