Start by making the orange layer: In a blender, combine 2 cups of fresh orange juice, 1/3 cup of granulated sugar, 1 cup of coconut milk, and 2 tablespoons of lemon juice. Blend until smooth. Pour the mixture into a shallow dish and freeze for about 1 hour to soften slightly.
While the orange layer is freezing, prepare the strawberry layer: Blend the pureed strawberries with 1/3 cup of sugar until smooth. Mix in 1 cup of coconut milk and 1 teaspoon of vanilla extract. Once the orange layer is mildly set, pour the strawberry mixture over it and return to the freezer for another hour.
While the second layer is freezing, make the blueberry layer: Blend the pureed blueberries with 1/3 cup of sugar and a pinch of salt. Add the remaining 1 cup of coconut milk and stir well. After an hour, pour this layer over the strawberry layer.
Cover the dish with plastic wrap or a lid and freeze the entire mixture for at least 4 hours or until fully firm.
To serve, let the sherbet sit at room temperature for a few minutes to soften slightly, then scoop into bowls or cones and enjoy your colorful creation!
