I peeled the pineapple and used a small melon ball tool to take out the brown corns which left little holes. This is what caused the pineapple to look as if it had petals.
I thinly sliced the pineapple and placed the pieces on the dehydrator tray.
I dehydrated these for about five hours at 105 degrees then flipped them for the same amount of time. As they became dry the edges curled up like real petals. I also noticed that the edges turned a deeper yellow.
