1/2 cup of milk
1 teaspoon of vanilla extract
1 tablespoon of sugar
2 cups of ice
6 tablespoons of salt

Mix milk, vanilla, sugar in sandwich bag and seal tightly.
Mix ice and salt in quart or gallon bag.
Put sandwich bag in quart/gallon bag and seal tightly.
Shake it!
In 5 minutes, voila! Ice cream.
*whole milk works better than anything else.
*having a towel to wrap around the bag helps as it gets extremely cold.
*doesn't make enough for more than one. Consider doubling all the ingredients (except ice and salt)

**I'm also not sure if the measurements are different in the UK. If anyone can tell me if they are and what to convert them to, I'll look it up and edit this post. Sorry!
