The primary ingredient in cream cheese is dairy, specifically cream and milk. Cream cheese is a soft, spreadable cheese made from a mixture of cream and milk, which gives it a rich, creamy texture and a mild flavor. This cheese is a popular ingredient in various culinary applications, including spreads, dips, and desserts. To achieve its characteristic smoothness and slightly tangy taste, the mixture is pasteurized and then inoculated with specific bacteria that contribute to its flavor development during the fermentation process. Cream cheese is commonly used in both savory and sweet dishes, making it a versatile ingredient in many recipes.
