Chop the dragon fruit after removing its outer skin.
Take a mixie add dragon fruit, rose water and honey.
Blend well for a minimum of 6 minutes so that the seeds would get crushed well. The seeds cannot 100% crush even if you blend for 6 minutes. It is still fine as the seeds give a natural crunchiness.
After blending you might need to adjust the sweetness taste as the seeds would have crushed by now and the sweetness might have reduced.
Take a popsicle bag and a syringe or a funnel. Pour the juice into the popsicle bag.
Freeze it for a minimum of 8 hours or overnight
Notes
I used syringe as a fun activity with my kid. You may use funnel also.
Adjust the taste of honey as the taste of pitaya varies from variety to variety.
