1. Cut the watermelon into small pieces and remove the seeds. I cut the watermelon a bit bigger, and then cut the watermelon into smaller pieces after the ice.
2. Put it in a fresh-keeping box or fresh-keeping bag and freeze until completely hardened.
3. Take it out and put it in the food processor.
4. Break into pieces.
5. Pour out from the food processor, put it in a fresh-keeping bag or other container and freeze again until hard, take it out before eating, use a fork or use the back of a knife to break directly through the fresh-keeping bag, and eat as soon as possible.
