Place 1/2 cup cold water in a small bowl and sprinkle the gelatin over the top. Set aside until the gelatin sets and becomes a solid gel, about 10 minutes.
Bring the cream and sugar to a simmer. Whisk in the butter, yogurt, miso, vanilla and salt. Remove from the heat and stir in the gelatin. Using an immersion blender, puree the mixture, then strain through a fine mesh strainer.
Ladle or pour into 6-ounce serving bowls and chill in the refrigerator until set, 3 hours.
Serve cold with fresh fruit and whipped cream.
