1 3/4 cups (14 fluid ounces) cold water
1 tablespoon (8 g) unflavored powdered gelatin
1/4 cup (50 g) granulated sugar
About 1 ounce freeze-dried fruit, ground into a powder
1/4 cup + 1 tablespoon (2 1/2 fluid ounces) heavy whipping cream
In a small bowl, place about 2 tablespoons of the water and sprinkle with the powdered gelatin. Mix thoroughly and allow to sit until the gelatin swells in the liquid.
Place about 1 cup of the remaining water in a medium, heavy-bottom saucepan over medium heat and bring it to a simmer. Add the sugar and freeze-dried fruit powder, and whisk to combine well. Add the swelled gelatin and whisk constantly until the gelatin is completely melted. Remove the saucepan from the heat and transfer the mixture to a medium-sized bowl. Add the remaining cold water, and whisk to combine well. Place the bowl in the refrigerator (for about 1 1/2 hours) or freezer (for about 30 minutes) until the gelatin is beginning to set. It will cling to the sides of the bowl as you rotate it.
Remove the chilled gelatin from the refrigerator or freezer. Whip with a handheld mixer, for about 3 minutes or until the mixture froths and begins to lighten in color as a result of incorporating air into the mixture. Add the cream, and whip again until completely combined and the mixture is increased by about 50% from its original volume. Transfer the mixture to serving bowls or jars, cover each container and refrigerate until fully set (about another 2 hours). Serve chilled.
