Cut the fruit in half with a sharp knife. Use a spoon to scoop out the pulp from each half of the fruit. Scrape the inside of the fruit shell with the spoon to remove any remaining pulp. Discard the seeds and use the pulp as desired. Note that passion fruit pulp can stain clothing and countertops, so it's a good idea to work over a cutting board or bowl and to wear an apron or old clothes.
