Float

A float is a chilled beverage consisting of a scoop of ice cream or gelato floating in a carbonated soft drink. The most recognized version is the root beer float, but the concept extends to any pairing of soda and ice cream. The dish is believed to have originated in the United States in the late 19th century, with Robert McCay Green often credited for creating the first root beer float in Philadelphia in 1874.

Key ingredients are simple: a high-quality, dense vanilla ice cream and a crisp, flavorful soda. A great version is distinguished by the contrast between the cold, creamy ice cream and the effervescent, often sharp soda. The ice cream should be firm enough to float without immediately dissolving, creating a frothy, semi-frozen head as it melts. The ideal float is served in a chilled glass mug with a straw and a long spoon.

Regional variations are abundant. In the United Kingdom and Australia, a "spider" is made with ice cream and a soft drink like lime or cola. In Italy, the *cremolata* or *gelato con bibita* is popular, often using espresso or lemon soda. At Dylan's Diner in Casapulla, Italy, as featured by *Jana Food Porn*, the float is elevated with artisanal gelato and local Italian sodas, offering a refined take on the classic American treat.
