In a medium saucepan, combine the heavy cream, whole milk, granulated sugar, vanilla bean paste, and a pinch of salt. Place over medium heat, stirring constantly until the sugar dissolves completely and the mixture is hot but not boiling, about 5-7 minutes.
While the cream mixture is heating, prepare the gelatin by sprinkling it over the cold water in a small bowl. Allow it to sit undisturbed for about 5 minutes to bloom.
Once the cream mixture reaches the desired temperature, remove it from the heat and stir in the bloomed gelatin until fully dissolved and smooth.
Allow the mixture to cool slightly for about 10 minutes, stirring occasionally to prevent a skin from forming.
Carefully pour the mixture into individual serving cups or ramekins, filling them evenly.
Cover each cup with plastic wrap and refrigerate for at least 4 hours, or until set and firm to the touch.
To serve, gently run a small knife around the inside edge to loosen. Optionally invert onto a plate and garnish with fresh berries and a sprig of mint.
Notes
For an elegant touch, serve in clear glass cups to showcase the creamy texture.
