The recipe is simple: soda water, syrup, and a scoop of ice cream. There are many variations of syrup and ice cream, each creating a special flavor of ice cream soda. Make yourself one to celebrate National Ice Cream Soda Day, June 20th.
Also called a float, because a scoop or two of ice cream floated in the water, the ice cream soda was born in 1874.
In the late 19th century, ice cream was widely available through street vendors and at ice cream parlors. In 1874, the concept of the American “soda fountain” and the profession of the “soda jerk” emerged with the invention of the ice cream soda.
More about the invention of the ice cream soda follows.
It owes its creation to the soda fountain, a fixture of pharmacies that was the place to go in towns across America, long before there were coffee shops or other places for a snack in every neighborhood.
By 1895 there were more than 50,000 soda fountains in the United States and virtually every one of them was serving ice cream soda, and more than 60 flavors of syrup* available [source].
So even with just vanilla ice cream, there were plenty of flavors to be made.
Before the 1890s, the ice cream soda was made with sweet cream instead of ice cream†.
WHO INVENTED THE ICE CREAM SODA?
There are three claimants.
Detroit: In 1875, Fred Sanders substituted ice cream for the sweet cream on a hot summer day when the sweet cream kept turning sour from the heat. Word spread around Detroit, and then around the country. Although the Detroit Historical Society 0says that it is likely the ice 12.o Detroiters.
Elizabeth, New Jersey: One day, Philip Mohr decided to add a scoop of ice cream to his sarsaparilla soda, and liked the result. More importantly, the customers at his soda fountain liked it. So Mohr advertised his new ice cream soda with a sign outside the store and the drink took off.
Philadelphia: Robert McCay Green, Sr., is most often cited as the inventor. His own account, published in Soda Fountain magazine in 1910, states that while operating a soda fountain at the Franklin Institute’s 50th-anniversary celebration in 1874, he wanted to create a new treat to attract customers away from another vendor who had a fancier, bigger soda fountain. After some experimenting, he decided to combine ice cream and soda water. During the celebration, he sold vanilla ice cream with soda water and a choice of 16 different flavored syrups.
Alas, competitors soon began selling the new sensation. Green’s will instructed that “Originator of the Ice Cream Soda” was to be engraved on his tombstone [source].
Customers went wild for the ice cream soda. But not so, the soda fountain manager or pharmacy owner.
According to the Dr. Pepper Museum, soda fountains wanted to get their customers in and out. The ice cream soda fought against that:
It took longer to make.
It required a freezer case for the ice cream frozen.
Patrons stayed longer to consume it.
What is unfathomable to us now, some fountain managers went as far as refusing to serve them unless there were empty seats in the fountain!
Fortunately, they couldn’t resist the ice cream soda-thirsty throngs for long. A paradigm shift occurred:
The soda fountain became known for ice cream soda.
In 1910, the modern electric milkshake machine was invented by Frederick J. Osius and commercialized by his company, Hamilton Beach, under the name Cyclone Drink Mixer. Let the milkshakes, malts (a milkshake with malt powder), and frappés begin!
