1Begin by preparing the blue watermelon slices. If they are not already pureed, blend them until smooth.
In a mixing bowl, combine the pureed blue watermelon with the gummy juice and honey. Stir until the honey is completely dissolved and the mixture is well combined.
Taste the mixture and adjust the sweetness if necessary. If it's too sweet, you can add a little bit of lemon juice to balance the flavors.
Pour the mixture into an ice cream maker and churn according to the manufacturer's instructions. If you do not have an ice cream maker, you can pour the mixture into a shallow dish and place it in the freezer.
If using the freezer method, stir the sorbet every 30 minutes to break up any ice crystals until it is uniformly frozen and has a sorbet-like texture. This may take about 3 to 4 hours.
Once the sorbet is ready, scoop it into bowls or cones and serve immediately. If the sorbet is too hard, let it sit at room temperature for a few minutes to soften before serving.
