If you have a craving for ice cream but don't have any on hand you can make it yourself if you have cream and a few standard pantry staples on hand. YouTube user daffyskies demonstrates how you can make ice cream in 10 minutes by placing your ingredients in a litre-sized freezer bag and putting it inside a 3.7L freezer bag with ice and salt and shaking.
For two servings of vanilla ice cream you'll want to place a cup each of milk and cream into the smaller bag along with 1/2 teaspoon of vanilla extract and three tablespoons of sugar. Seal this bag and place it inside the larger one and fill it with ice and up to eight teaspoons of salt. Seal that bag and shake them both for 10 minutes. The salt will lower the freezing temperature of the ice which will allow it to freeze the thin layer of ice cream.
