Overview

Condensed milk is cow's milk from which water has been removed (roughly 60% of it). It is most often found with sugar added, in the form of sweetened condensed milk, to the extent that the terms "condensed milk" and "sweetened condensed milk" are often used interchangeably today. Sweetened condensed milk is a very thick, sweet product, which when canned can last for years without refrigeration if not opened. The product is used in numerous dessert dishes in many countries.

A related product is evaporated milk, which has undergone a lengthier preservation process because it is not sweetened.

History

According to the writings of Marco Polo, in the thirteenth century the Tatars were able to condense milk. Marco Polo reported that 10 lb of milk paste was carried by each man, who would subsequently mix the product with water. However, this probably refers to the soft Tatar curd (qatiq), which can be made into a drink (ayran) by diluting it, and therefore refers to fermented, not fresh, milk concentrate.

Nicolas Appert condensed milk in France in 1820 and in 1835, English civil engineer William Newton added sugar as an additional measure of preservation. Before these developments, milk could be kept fresh for only a short while and was available only in the immediate vicinity of a lactating cow. While returning to the United States from a trip to England in 1851, Gail Borden Jr. was devastated by the deaths of several children, apparently from poor milk obtained from shipboard cows. With less than a year of schooling and following a series of failures, both of his own and of others, Borden was inspired by the vacuum pan he had seen being used by Shakers to condense fruit juice and managed to reduce milk without scorching or curdling it.

Even then his first two factories failed and only the third, built with new partner Jeremiah Milbank in Wassaic, New York, produced a usable milk derivative that was long-lasting and needed no refrigeration.

Probably of equal importance for the future of milk production were Borden's requirements (the "Dairyman's Ten Commandments") for farmers who wanted to sell him raw milk: they were required to wash the cows' udders before milking, keep barns swept clean, and scald and dry their strainers morning and night. By 1858, Borden's milk, sold as Eagle Brand, had gained a reputation for purity, durability and economy.

Production

Raw milk is clarified and standardised to a desired fat to solid-not-fat (SNF) ratio, and is then heated to 85 – 90 C for several seconds. This heating process destroys some microorganisms, decreases fat separation and inhibits oxidation. Water is evaporated from the milk and sugar is added until a 9:11 ratio of sugar to (evaporated) milk is reached. The sugar extends the shelf life of sweetened condensed milk. Sucrose increases the liquid's osmotic pressure, which prevents microorganism growth. The sweetened evaporated milk is cooled and lactose crystallization is induced.

Current use

Condensed milk is used in recipes for the Brazilian candy brigadeiro (where condensed milk is the main ingredient), key lime pie, cheesecakes, caramel candies, and other desserts. Condensed milk and sweetened condensed milk are also sometimes used in combination with clotted cream to make fudge in certain countries such as the United Kingdom.

In parts of Asia and Europe, sweetened condensed milk is the preferred milk to be added to coffee or tea. Many countries in Southeast Asia, such as Vietnam and Cambodia, use condensed milk to flavor their hot or iced coffee. In Malaysia and Singapore, teh tarik is made from tea mixed with condensed milk, and condensed milk is an integral element in Hong Kong tea culture. In the Canary Islands, it is served as the bottom stripe in a glass of the local café cortado and, in Valencia, it is served as a café bombón. In Myanmar, condensed milk is an essential part of a vast majority of beverages such as coffee, milk tea and fruit juices along with the use of it as a sweetener in many desserts such as popsicles.

Borden's Eagle Brand sweetened condensed milk has noted that ice cream could be made quite simply at home with their product, cream, and various simple flavorings, being ready to serve after as little as four hours.

In New Orleans, sweetened condensed milk is commonly used as a topping on chocolate or similarly cream-flavored snowballs. In Scotland, it is mixed with sugar and butter and then boiled to form a popular sweet candy called tablet or Swiss milk tablet, this recipe is very similar to another version of the Brazilian candy brigadeiro called branquinho. In some parts of the Southern United States, condensed milk is a key ingredient in lemon ice box pie, a sort of cream pie. In the Philippines, condensed milk is mixed with some evaporated milk and eggs, spooned into shallow metal containers over liquid caramelized sugar, and then steamed to make a stiffer and more filling version of crème caramel known as leche flan, also common in Brazil under the name pudim de leite.

In Mexico, sweetened condensed milk is one of the main ingredients of the cold cake dessert (the leading brand is "La Lechera", the local version of Swiss Milchmädchen or La Laitière by Nestlé), combined with evaporated milk, Marie biscuits, lemon juice, and tropical fruit. In Brazil, this recipe is also done by exchanging fruit for puddings, most commonly vanilla and chocolate, known as pavê or torta de bolacha. It is also used to make homemade dulce de leche by baking it in an oven. In Brazil, this is done by baking the unopened can in a bain-marie, the result being doce de leite. In Britain and Ireland, the contents of a boiled can are used as the layer between the biscuit base and the banana and cream level in banoffee.

Substitutions

Condensed milk can be made from evaporated milk by mixing by weight, for every 100 grams of evaporated milk, 82 grams of white sugar (for a condensed milk comprising 45% added sucrose) or 85 grams of white sugar (for approx 46% content of sucrose). The homemade preparation is heated gradually until sugar is fully dissolved then it is cooled and stored in a container.
