Legend has it that the Roman emperor, Nero, is credited as the first person to make ice cream. Nero commanded slaves to bring snow down from the mountains, which was then used to freeze the flavored cream mixture. The secret was to lower the freezing point of ice in order to freeze the cream. How? The scientific secret is salt! Here’s a scientific recipe that you can use at home to make your own ice cream.
- Large (1 gallon) plastic jar (a coffee can works, too)
- 2 quart-size zipper-lock bags
- Half & Half
- Crushed ice (or snow in the winter!)
- Rock salt
- Towel (or winter gloves)
