Sprinkle gelatin over 3 tbsp milk. Stir gently and leave it aside for 10 minutes.
Heat the remaining 1 tbsp milk. I allow it to heat up for 20 seconds in the microwave oven.
Add the saffron and allow it to infuse.
In the meantime, puree the mango in a food processor or blender.
Strain it with a sieve if the puree has fibres.
Add lemon juice,cardamom and saffron to the mango puree and mix well.
Add sugar to the whipping cream.
Whip till it forms soft peaks.
Heat the gel mixture and stir till the gel melts completely. I allowed it to heat up in the microwave oven for 15 seconds.
Pour the gel mixture into the mango puree mixture and mix well.
Fold in the whipped cream into the mango puree mixture.
Divide the mousse between 4 bowls or glasses.
Cover the bowls or glasses with cling film or small lids.
Put it in the fridge and allow the mousse to set at least for 8-12 hours or overnight.
Top with chopped mango and passion fruit pulp before serving.
