<P> In 1843, Nancy M. Johnson invented the first ice cream maker with a crank on the outside of the wooden tub . The crank mixes the ice cream, while also scraping the frozen ice cream off of the sides of the pot . Before 1843, making ice cream required more time . The crank on the outside of the wooden tub eliminates the step of removing the pot from the wooden tub to scrape the sides of the pot of frozen ice cream . After the creation of Nancy Johnson's invention, commercial ice cream companies started to use ice cream makers powered by "horse - powered treadmills, steam engines, and finally electric motors". People who made ice cream at home began using electric ice cream makers as well . Ice cream production was more popular when sugar became cheaper and ice was easier to attain . After the Civil War ended, ice cream prices had decreased, and more wholesalers had joined the ice cream making business . </P> <P> Ice cream is flavored by artificial or natural vanilla flavoring . Artificial flavorings contain 100% vanillin, the main ingredient that contributes to natural vanilla extract's flavor . Natural vanilla extract also contains nearly 200 more compounds in addition to vanillin . The different chemical properties of these compounds may cause compatibility issues with different ice cream preparations . Vanilla ice cream may be classified by the type of flavoring used . If natural vanilla extract is used, then the product is called "vanilla ice - cream". If vanillin from natural vanilla is used, then the product is called "vanilla flavored ice cream". If artificial vanillin is used, then the product is labelled as an "artificially flavored vanilla ice - cream". The United States Food and Drug Administration characterizes vanilla ice cream into three categories . Category I ice cream only contains vanilla extract . Category II ice cream contains 1 ounce (28 g) of synthetic vanilla per gallon (3.8 l) of 1-fold vanilla extract . Category III only contains synthetic ingredients . </P>
