In a saucepan, heat the passion fruit puree, orange juice, and sugar until dissolved.
Add the gelatin to the hot juice and stir to melt and combine. Strain the liquid into a bowl and place it over an ice bath. Stir it constantly with a rubber spatula and when it just starts to set, fold in the whipped cream. Pour this into soup plates or dessert bowls and chill. If storing them overnight, cover them with plastic wrap.
To serve the mousse, remove the bowls from the refrigerator. Peel and slice the bananas in half longways and dip their faces in coarse sugar and caramelize them under a broiler or with a blowtorch. Place them on the mousse fanning them then tuck in a few half slices of kiwi.
