For the elderflower puree, grind the rice pudding in a blender, boil the elderflower in the milk and let it steep briefly. Then strain through a sieve.
Put the flavored milk back on the stove, add stevia (if you prefer to sweeten properly take honey) and the rice flour, stirring constantly until the milk covers.
Divide among small compote bowls and let stand. Serve with fresh cherries or cherry compote.
