Egg yolks have been integrated into ice creams since at least the 1690s, though there are several notable invention stories that are associated with modern commercializations of this practice.
One early commercialization of Frozen custard was in Coney Island, New York in 1919, when ice cream vendors Archie and Elton Kohr found that adding egg yolks to ice cream created a smoother texture and helped the ice cream stay cold longer. In their first weekend on the boardwalk, they sold 18,460 cones.
A frozen custard stand at the 1933 World's Fair in Chicago introduced the dessert to a wider audience. Following the fair, the dessert's popularity spread throughout the Midwest; Milwaukee, Wisconsin, in particular, became known as the "unofficial frozen custard capital of the world".
Per capita, Milwaukee has the highest concentration of frozen custard shops in the world and the city supports a long-standing three-way competition between Kopp's Frozen Custard, Gilles Frozen Custard and Leon's Frozen Custard.
One of the fastest growing frozen custard chains in the country is Andy's Frozen Custard. Based in Springfield, Missouri, Andy's has 30+ locations in Missouri, Arkansas, Illinois, Texas, Oklahoma, and will soon open stores in Tennessee and Colorado.
Other frozen custard restaurants include Freddy's Frozen Custard & Steakburgers, a fast-casual, or quick-service, restaurant based in Wichita, Kansas with more than a hundred locations nationwide, and Culver's, a fast casual restaurant long-noted for its frozen custard, based in Prairie du Sac, Wisconsin and has outlets in Milwaukee and throughout the Midwest, Ted Drewes Frozen Custard in St. Louis, and Scooters Frozen Custard in Chicago. Frozen Custard is making its way to the northwest as well. There are several new independent shops such as Tommi's Ice Creams in Grants Pass, OR
Frozen custard is also very popular in Ohio, especially near Cleveland and Cincinnati. Whit's Frozen Custard and Mitchell's top the list for the southern end of the state; East Coast Custard and Webers supply the need for the northeastern region.
In the U.S., the Food and Drug Administration requires products marketed as frozen custard to contain at least 10 percent milkfat and 1.4 percent egg yolk solids. If it has a smaller percentage of egg yolk solids, it is considered ice cream.
True frozen custard is a very dense dessert. Soft serve ice creams may have an overrun as large as 100%, meaning half of the final product is composed of air. Frozen custard, when made in a proper continuous freezer will have an overrun of 15–30% depending on the machine manufacturer (an overrun percentage similar to gelato). Air is not pumped into the mix, nor is it added as an "ingredient" but gets into the frozen state by the agitation of liquid similar to whisking a meringue. The high percentage of butterfat and egg yolk gives frozen custard a thick, creamy texture and a smoother consistency than ice cream. Frozen custard can be served at −8 °C (18 °F), warmer than the −12 °C (10 °F) at which ice cream is served, in order to make a soft serve product.
Another difference between commercially produced frozen custard and commercial ice cream is the way the custard is frozen. The mix enters a refrigerated tube and, as it freezes, blades scrape the product cream off the barrel walls. The now frozen custard is discharged directly into containers from which it can be served. The speed with which the product leaves the barrel minimizes the amount of air in the product but more importantly ensures that the ice crystals formed are very small.
Frozen custard is usually prepared fresh at the place of sale, rather than stored; however, it is occasionally available in supermarkets or by mail order. Generally, modern frozen custard stands provide up to three different flavors per day: vanilla, chocolate, and a unique "flavor of the day." The older vintage custard stands tend to have a dozen or so standard flavors.
