- vanilla extract
- ice
- salt
- 1 small zip lock bag

Ingredient Notes and Substitutes
- Cream: The ice cream will work with full-cream milk as well
- Icing sugar: Honey or maple syrup will work too.
- Salt: Any salt is fine to use but it is essential for this recipe to work. The salt reduces the melting point of ice allowing the temperature of the ice water in the outer bag to fall a few degrees below freezing meaning it is cold enough to freeze the cream or milk into ice cream. If you try this experiment without ice you will find it won't work.
