If starting with a fresh, whole pineapple, twist off the green top and discard. Trim off the ends with a sharp knife and stand up the pineapple. Starting at the top, trim off the skin a section at a time by making downward slices. Trim off any hard parts and use a small knife to pick out the seeds. Discard the skin and seeds and rinse your cutting board. Rinse your knife and pineapple and pat dry. Stand up the pineapple, and starting to the right of the core, slice downward. Rotate the pineapple and continue slicing downward around the core. Discard the core and cut the remaining pineapple into chunks.Try this smoothie with coconut rum after 5 p.m.!
