Is it an urban myth or did Maggie Thatcher help invent whippy ice cream?
One important development in the 20th century was the introduction of soft ice cream. A chemical research team in Britain (of which a young Margaret Thatcher was a member)[17][18] discovered a method of doubling the amount of air in ice cream, which allowed manufacturers to use less of the actual ingredients, thereby reducing costs. This ice cream was also popular amongst consumers who preferred the lighter texture, and most major ice cream brands now use this manufacturing process.[citation needed] It also made possible the soft ice cream machine in which a cone is filled beneath a spigot on order. In the United States, Dairy Queen, Carvel, and Tastee-Freez pioneered in establishing chains of soft-serve ice cream outlets.
