Durian Mousse Filling
Ingredients
450g durian puree (about 1 - 1.5 durian)
20g gelatine
450g whipped cream

1. Boil puree and gelatin powder until gelatine powder dissolved.
2. Leave to cool outside, do not cool in the fridge.
3. Once cooled, fold in whipped cream.
4. With the use of a cake ring, assemble cake and durian mousse together.
5. Once assembled, store in fridge for 3 - 4 hours for filling to set.

I didn't decorate the exterior of my cake as I need to halve the cake for my colleagues. But you can decorate it with whipped cream on the exterior.

If you don't like durian, just switch the fruit. I tried Mango Mousse cake with the same recipe. Nice! Will post the recipe the next time I bake, 'cause it includes the Mango Mirror recipe for the top of the cake. I heard Honeydew Mousse is good too!
