Place the watermelon and lime juice into the bowl of your food processor. Blend everything together until smooth and creamy. You will need to stop and scrape down the sides of the bowl occasionally to ensure everything is well combined. Don't blend too long though. Otherwise the sorbet will get too soft.
Once you have a smooth creamy texture, taste it and adjust the sweetness if needed by adding more honey. Enjoy immediately or freeze for 3-4 hours, or until ready to serve.
Notes
If your watermelon sorbet mixture is icy and not blending smoothly, add some water (one tablespoon at a time) to help achieve a smoother consistency.
The ripeness of your watermelon will also affect the how icy your sorbet is, so be sure to use a nice ripe watermelon!
It is best to enjoy immediately or freeze for up to 4 hours.
Be sure to use a high-powered food processor or blender to break up the frozen watermelon! No ice cream machine needed!
