Start by cleaning your rhubarb to remove all dirt and soil.
Then cut them into smaller pieces.
Bring sugar, water, and glucose syrup to a boil in a pot.
Once all the sugar is dissolved, you can add your rhubarb.
Now, simmer your rhubarb in the liquid until tender. The smaller you cut them, the less time they need. It takes anywhere from 5-10 minutes.
Transfer everything to a blender and blend until you have a smooth and uniform mixture.
Chill it until completely cold, which takes 30-60 minutes.
Use an ice cream maker to churn the sorbet until frozen.
Now the sorbet is ready to be served or placed in the freezer.
