Bring the water to a simmer, dissolve the sugar, and allow to cool. If you’re planning to make all three flavours, prepare three separate batches of syrup. Blend one batch of fruit, baobab powder, and cooled syrup until smooth.
If you’re not sure the consistency is correct, before freezing the fruit mixture for the first time, test the sorbet’s consistency using an ‘egg test’. (Thanks to The Kitchn for this awesome tip!)
Gently lower a washed egg into the mixture; if it’s too thick, most of the egg will stick out above the surface. In this case, add more water. If the mixture is too runny, the egg will sink below the surface. In this case, add more sugar. If it’s the perfect consistency, about 2½ cm of the egg will be visible above the surface. Now pour the mixture into a freezer-friendly container or bowl.
