Condensed milk is a thick, sweet dairy product made by removing most of the water from cow's milk. This process involves heating the milk and adding sugar, which helps preserve it and gives it a rich flavor. It is commonly used in desserts, coffee, and various recipes around the world. There are two main types of condensed milk: sweetened condensed milk, which contains added sugar, and unsweetened condensed milk, which does not. Sweetened condensed milk is often used in recipes for pies, cakes, and candies, while unsweetened condensed milk is less common but can be used in savory dishes.
