I finally worked out a simple way to make creamy vanilla ice cream without an ice cream machine. The trick is sweetened condensed milk. The sugar content prevents the formation of ice crystals.
Ingredients:
One 395gm can of sweetened condensed milk. I used the light version.
1 teaspoon vanilla essence.
method:
Add the vanilla to the cream and whip it to soft peaks. (I just plused the cream in my Ninja blender)
Continue to whip while adding the condensed milk.
Place in the freezer over night and in the morning you should have some creamy vanilla ice cream.
