French pots. But after the war, commercial refrigeration and more sophisticated ice cream makers came along, and batch freezers disappeared. With the continuous commercial freezers, the mix of cream, sugar and eggs was poured in and quickly whipped with fast-moving beaters. These machines continuously spit out the ice creamâbasically the antithesis of Graeterâs.
At Graeterâs, the mix was cranked in small batchesâeven today, a batch of Graeterâs makes only two and a half gallonsâand had to be scraped by hand from the sides of the pots and hand-packed into cartons. The Graeterâs method incorporated the least amount of air into the ice cream, making it more dense and luxurious.
Dick Graeter remembers trying to make Graeterâs Ice Cream in one of the newer ice cream makers when he joinedthe company in the 1950s. âYou couldnât make the product that we were making in that type of a freezer. It would turn it into butter,â Dick said. âI tried that several different times when I came here.â
The new machines created a version of ice cream that was lighter in texture and airier than Graeterâs. By law, ice cream could have as much as 100 percent overrun, or be as much as 50 percent whipped-in air. It was, in essence, frozen foam. Graeterâs had (and still has) only a small amount of air that inevitably gets mixed in during the freezing process, just between 20 and 25 percent. A pint of Graeterâs weighs almost a pound, whereas the competitionâs ice cream might weigh half as much.
Dick insists it wasnât just a pure love of the product that kept them from giving up the labor-intensive French pot method for a perhaps more lucrative continuous freezer version. âI always said that we were too dumb to make the next step, didnât know any better.â
The changes in ice cream production came hand in hand with the onset of commercial dairy farms. The number of small dairy farms dwindled starting in the 1930s for more than fifty years because it became cost-prohibitive. Dairy farmers figured out what to feed cows to get the maximum output in milk. The annual average yield per cow rose from 3,000 pounds in 1890 to 4,500 pounds in 1950.
Insulated trucks led to larger milk-processing plants, which could process the milk at a much lower cost. Dairy products, including the milk and cream needed for ice cream, decreased in price. For dairy farms to make money, they needed bigger operations.
Local competition in ice cream increased with the introduction of United Dairy Farmers (UDF) in the 1940s. Started by Carl H. Lindner Sr. and carried on by his children, the group started one of the first dairy stores, where milk and other dairy products, including ice cream, were sold instead of home delivered. Despite growing popularity and convenience, the UDF ice cream was made by the continuous method, making the product a far cry from the hand-packed, dense ice cream made at Graeterâs.

Another change to the ice cream industry was the introduction of soft serve, which became possible because of new equipment that hadnât been available until this time. âThere was a soft serve place on every corner after the war,â Dick said. âIt really put the ice cream businesses like ours out of business. All ice cream like ours was sold in drugstores. There wasnât a drugstore anywhere that didnât have an ice cream fountain.â Soft serve, sometimes referred to as frozen custard, was new and differentâand widely available.
Like many culinary inventions, the history of soft serve is not definite. More than one claim to its creation exists. In oneversion, the silky smooth semi-frozen mixture was created by the founders of Dairy Queen, J.F. McCullough and his son, Alex, in Davenport, Illinois,
