Bloom the gelatin by sprinkling it over 1/4 cup cold water in a small bowl. Let it sit for 5 minutes without stirring.
Warm your chosen liquid base in a saucepan over low-medium heat until just warm, not boiling.
Add the bloomed gelatin to the warm liquid and whisk gently until fully dissolved.
Stir in sweetener and any flavorings like vanilla extract, citrus zest, or cocoa powder.
Pour the mixture into molds, cups, or a dish. Add fruit pieces if using.
Refrigerate for at least 3 hours or until fully set before serving.
