Steps
1. Soak the gelatin sheet in cold water for 5 minutes (if using powdered gelatin, sprinkle over 2 tbsp cold water and let bloom).

3. Remove from heat and stir in the softened gelatin until fully dissolved.
4. Mix in the mango puree gently.
5. Pour the mixture into a serving glass or mold and refrigerate for at least 4 hours until set.
6. Before serving, spoon the passion fruit pulp over the set panna cotta.
7. Garnish with mint leaves if desired and serve chilled.
