Wash the fruit and soak it in 1250 ml of water for 12 hours.
Then bring the fruit to the boil with the soaking water, the lemon aroma and the cinnamon and cook over a low heat for 30 minutes until soft. Strain the soup through a sieve, bring to the boil again and bind with the mixed cornstarch. Pour in the vanilla sugar, season the soup with sugar and add macaroons if you like.
