I have not added additional sugar since the powder is already sweet. Add sugar as needed.
If using whipping cream, use 250 ml, add sufficient sugar to taste and beat till stiff, before proceeding with the rest of the steps. DO NOT use the milk, since it is only for the powder to whip.
With this amount of gelatin, the cheesecake is soft. If you want it a little sturdier, add an additional tbsp gelatin.
