In a medium sized bowl mix together the Strawberries and Rhubarb and place them in the PacoJet beaker.
In a separate small bowl dry mix the allulose and perfect sorbet. While whisking slowly add the allulose mixture to the water and whisk until dissolved.
Pour the water and allulose mixture into the pacojet beaker.
Freeze this mixture solid. It may take between 4-6 hours. If the mixture isn’t frozen solid it will be too soft.
Once frozen, place the PacoJet beaker into the container. Place the PacoJet gasket and blade on the PacoJet.
Churn the sorbet and serve immediately.
