What Surprising Ingredient Was Once Used to Make Ice Cream?

In the 18th century, before the advent of modern refrigeration and the widespread use of sugar, ice cream was often made using an unusual ingredient: salt. Early recipes would combine ice with salt to create a supercooled environment, which helped freeze the creamy mixture. Salt lowers the freezing point of ice, allowing the ice cream base to freeze more effectively and achieve a smooth texture. This method not only enhanced the freezing process but also contributed to the unique flavor profile of the dessert. Over time, as ice cream became more popular and accessible, the reliance on salt diminished, but its role in the early days of ice cream production highlights the innovative techniques used by our culinary ancestors to create delightful treats.
