Pour 100 ml of milk into a mixing bowl and mix with the cornstarch.
In a saucepan, bring the remaining milk to a boil with the sugar and the scraped out inside of the vanilla bean.
When the milk boils, add the starch mixture and stir well with a whisk for a minute, then remove the pudding from the heat and pour it into a pudding mold, in this case a ring mold.
The pudding must set in the refrigerator for about 2 hours, then you can serve it garnished with the drained compote fruits.
