Vanilla ice cream can be made without the use of a machine. First find an appropriate recipe that lists ingredients and the measured amounts of the ingredients.
The first step is to create the mixture following the recipe. That mixture then needs to be frozen in an ice bath while also freezing another container for use later. Once the mixture starts to freeze, transfer it to the frozen bowl. The mixture then needs to be whipped to break up any forming ice crystals. Repeatedly whip the mixture every half hour in order to keep it smooth. Once the mixture has frozen to the desired consistency, enjoy!
