Condensed milk, also known as sweetened condensed milk, is cow's milk from which water has been removed and to which sugar has been added, yielding a very thick, sweet product which when canned can last for years without refrigeration if unopened. The two terms, condensed milk and sweetened condensed milk, have become synonymous. Though there have been unsweetened condensed milk products, today these are uncommon. Condensed milk is used in numerous dessert dishes in many countries, especially in Brazil and also Russia.
