Bring the milk to a boil. Add rice flakes to the boiling milk and agar and cook for about 2 minutes, stirring from time to time.
Leave the flakes to cool for a while. Then add agave syrup and vanilla extract (vanilla seeds) and blend to get a smooth mixture. Pour the mixture into a glass/serving dish.
Blend raspberries with agave syrup and pour over the rice mixture.
Garnish with fresh raspberries/ sprig of mint etc. Refrigerate until fully set: at least 1 hour. Enjoy!
