In the United States, ice cream made with just cream, sugar, and a flavouring (usually fruit) is sometimes referred to as "Philadelphia style"ice cream. Ice creams made with eggs, usually in the form of frozen custards, are sometimes called "French" ice creams or traditional ice cream.
American federal labeling standards require ice cream to contain a minimum of 10% milk fat (about 7 grams (g) of fat per 1/2 cup [120 mL] serving), 20% total milk solids by weight, to weigh no less than 4.5 pounds per gallon (in order to prevent consumer fraud by replacing ingredients with air), and to contain less than 1.4% egg yolk solids. Federal government regulations pertaining to the process of making ice cream, allowable ingredients, and standards, may be found in Part 135 of Title 21 of the Code of Federal Regulations.
Ice cream is an extremely popular dessert in the United States. Americans consume about 15 quarts (more than 13 liters) of ice cream per person per year — the most in the world. As a foodstuff it is deeply ingrained into the American psyche and has been available in America since its founding in 1776: there are records of Thomas Jefferson serving it as a then-expensive treat to guests at his home in Monticello. In American supermarkets it is not uncommon for ice cream and related products to take up a wall full of freezers.
Although chocolate, vanilla, and strawberry are the traditional favorite flavors of ice cream, and once enjoyed roughly equal popularity, vanilla has grown to be far and away the most popular, most likely because of its use as a topping for fruit based pies and its use as the key ingredient for milkshakes. According to the International Ice Cream Association (1994), supermarket sales of ice cream break down as follows: vanilla, 28%; fruit flavours, 15%; nut flavours, 13.5%; candy mix-in flavours, 12.5%; chocolate, 8%; cake and cookie flavours, 7.5%; Neapolitan, 7%; and coffee/mocha, 3%. Other flavours combine for 5.5%. Sales in ice cream parlors are more variable, as new flavours come and go, but about three times as many people call vanilla their favorite than chocolate, the runner-up.
