Add the jelly powder to a bowl and pour over ¾ cup of boiling water. Stir until completely dissolved and smooth, with no granules remaining.Note: If the jelly feels grainy, place the bowl over a double boiler and gently heat while stirring until smooth. Set the dissolved jelly aside and allow it to cool to room temperature.Note: Adding hot jelly to the cottage cheese can cause the proteins to clump and the jelly to form granules. In a separate bowl, mix the cottage cheese and condensed milk until smooth and well combined.
Once the jelly has cooled, add it to the cottage cheese and condensed milk mixture. Stir gently until combined.
In another bowl, whip the fresh cream until soft peaks form. Do not overwhip, as this can cause the cream to split.
Gently fold the whipped cream into the cheesecake mixture, being careful not to overmix. This helps keep the filling light and airy.
Pour the cheesecake mixture over the prepared biscuit base. Smooth the top with a spatula.
Refrigerate overnight, or until fully set (6 - 8 hours).
Before serving, spoon the granadilla (passion fruit) pulp over the top to decorate.
