Stone fresh cherries and place in a blender with the coconut milk and sugar. Mix, then strain over a bowl and press as much and as best you can through the sieve. Put it back in the blender and add the yogurt and cream. Mix well and serve the shake in two large glasses.
Strain the cherries from the glass, collect some of the juice and add to the shake. You can also use natural yoghurt, but then you should increase the amount of sugar.
