1. I didn't add any sugar into this icecream as the whipping powder pack and the rose syrup gave it sufficient sweetness.
2. If you are opting to use packed whipping cream, the quantity to use would be 1 litre, add around 1/2 to 1 cup granulated sugar depending on your level of sweetness as well as the sweetness of the rose syrup (some rose syrups are horribly sweet!!!!) and whip till done.
3. To granulate sugar, simply powder your normal sugar in your grinder! :)
