Add the 1½ tablespoon of water to a small bowl and sprinkle the gelatine powder evenly over top. Set aside for about 10 minutes to allow the gelatine to bloom.
In a large bowl, whisk together ¾ cup of the heavy cream with the yoghurt and vanilla bean paste and set aside.
In a saucepan, heat the remaining ¾ cup of cream with the sugar over a medium heat, stirring until the mixture is simmering and the sugar has dissolved.
Remove the pan from the heat and add the softened gelatine and stir until dissolved.
Slowly pour the heated mixture into the bowl with the yoghurt and cream, whisking to combine.
Ladle the mixture evenly into four glasses or decorative tea cups. Cover these with cling film and refrigerate for about 4 hours (or overnight) until set.
To serve, remove the cling film and spoon the chilled compote evenly on top of each.
