Peel off 250g of durian pulp, approximately 5-7 pieces according to the fruit size.
Put half (130g) into a blender/food processor, then blend until smooth.
In another bowl, pour in cold whipping cream.
Prepare an ice bath, then place the whipping cream over it.
Add in vanilla extract.
Whip on high speed, stop once the cream has soft peaks.
Add in condensed milk, blended durian pulp and a pinch of salt (optional).
Whisk on low speed until well mixed.
Add in the remaining 120g of peeled durian pulp and lightly mix it in.
In a large enough container, pour in the durian ice cream mixture.
Lightly tap to even out the ice cream mixture.
Close the container tightly, then store it in the freezer overnight.
