Wash the potatoes and carrots, peel them and cut them into cubes and cook in the carrot juice for about 20 minutes. Stir in the millet flakes and simmer for 3 minutes. Whisk the eggs, add and bring to the boil again while stirring. Then add orange juice and rapeseed oil and puree everything with a hand blender.
Freeze in portions. Ice cube makers are very suitable for this.
