Wash 3 fruits with hot water and thinly remove the skin from the pulp. Now halve all the fruits in the middle and squeeze out the juice. Briefly press the cardamom with a spoon so that the capsules are open. Mix all ingredients with the juice and cook for about 10 minutes until a syrup is formed.
Pour the mixture through a sieve and let it cool down. Stir in the wheat grain and bottle everything.
