This makes 7 x 140g Sinchies for this experiment OR you can make it in the 1lt bag and freeze it in the freezer (that is what we did).
Place condensed milk, cream, milk and vanilla extract into a 1L Sinchies Reusable Food Pouch.
Place ice cubes into the large zip-lock bag with the rock salt.
Place the 1L Sinchies Reusable Food Pouch into the large zip-lock bag.
Shake for 5-10 minutes until you get the consistency of ice cream (Do this outside as it can get a bit wet as the ice melts)
Once done you can eat it straight away (You can add fruit and lollies to have a variety of flavours)
