Key Lime Ice Cream is a tangy, creamy frozen dessert that captures the bright, aromatic flavor of Key limes, which are smaller and more floral than common Persian limes. The typical ingredients include Key lime juice, zest, cream, sugar, and often egg yolks for a custard base. It is a beloved treat strongly associated with the Florida Keys, especially Key West.
As a rich dessert, it is high in fat and carbohydrates, with minimal protein. A standard half-cup serving provides a good dose of vitamin C from the lime juice and typically ranges from 200 to 300 calories.
