Wash the rhubarb, cut off the ends, peel, cut the stalks diagonally into pieces approx. 1.5 cm wide and place in a low saucepan.
Wash and clean the strawberries, cut into large cubes, mix with powdered sugar, water and vanilla pulp and mix very finely with the hand blender. Then pour over the rhubarb pieces. Bring to the boil over moderate heat and cook covered for 2-3 minutes, remove from heat and let the rhubarb compote cool.
Mix the cold rhubarb compote with the yogurt. Fill glasses with crushed ice, fill up with the rhubarb smoothie and garnish with strawberries.
