One might think that condensed milk is simply a jar full of milk and sugar, basically the label is clear. Instead, reality is a little more complex and surprising. Inside that creamy container there is a small concentrate of history, food technology and gastronomic culture which, with discretion, has revolutionized kitchens from all over the world.
Origin and diffusion
Condensed milk was born from a precise need: to preserve a perishable food like milk for a long time, keeping the nutritional properties. It was 1853 when Gail Borden, an American entrepreneur and inventor, patented its industrial production, reducing the quantity of water of fresh milk and adding sugar in large quantities to create a hostile environment for bacteria. During the American civil war, condensed milk became a precious ally of the soldiers, transforming itself from a niche product to extremely popular ingredient.
Today it is used for desserts, Vietnamese coffee, South American desserts, ice cream and drinks, becoming over time a sort of “secret ingredient” that gives creaminess and sweetness, without the anguish of a short -term deadline.
How is condensed milk really produced?
As mentioned, condensed milk is not simply milk with sugar mixed at home. Why?
The answer lies in the evaporation process. To make the condensed milk, the low pressure milk is warmed in large tanks, the water is reduced to about 60% of the initial volume, while the sugar (generally about 40-45% of the final weight) is added hot, completely dissolving in the tactful mass. In this way a viscous, stable product is obtained, which does not crystallize and which resists thermal changes, thanks to the homogeneous structure.
If inside the home walls you have to try to mix milk and sugar, you would get a sweet liquid, but not the same consistency or the same shelf life. The condensed milk, in fact, thanks to controlled evaporation, also undergoes a partial caramelization of lactose, which gives that ivory color and that slightly toasted, unmistakable flavor.
Why do you keep so long?
Then there is a question of food safety: the high sugar concentration, combined with the reduction of water, prevents bacterial proliferation. It is one of the reasons why condensed milk can remain in the pantry for months, if not years, without undergoing alterations, as long as the package remains intact.
Condensed milk or evaporated milk?
It should not be confused with evaporated milk, which does not contain sugar but is obtained with the same principle of evaporation. The evaporated milk has a more neutral flavor, a clearer color and is often used to cook savory dishes, while condensed, sweet and intense milk, it is the king of desserts, from cold cakes cheesecakes, to coconut biscuits and homemade spreads.
An ingredient that smells of memories (and new recipes)
Many will remember the dairy products condensed in the grandmother’s pantry – the product arrives in Italy in 1914 – ready to turn into last minute desserts: it was enough to pour a spoon on the bread, or mix it with cocoa to obtain a snack from real ghiletons.
Beyond the nostalgia factor, condensed milk is synonymous with practicality, a creative ingredient for those who love to experiment in the kitchen. In many South American countries it is used to prepare the Dulce de leche, simply by boiling the can for hours until the content becomes a caramel -colored cream.
It is not just milk and sugar: it is magic in can
Then, the next time you happen to you in your hands a condensed can of milk, remember that it is not only milk and sugar, but a sort of magic of food engineering. A product born from an ancient need that today continues to find space between the shelves of supermarkets and home dishes, ready to give sweetness to a cold coffee, a handmade ice cream and a dessert to be prepared on the fly
If you want to experiment, try making a cocoa spreadable cream at home starting from condensed milk, with the addition of bitter cocoa and a spoonful of butter. You can discover, spoon after spoon, because this creamy delight is not at all a simple mix of milk and sugar, but a concentrate of pleasure that brings with it a long history, a small secret to be rediscovered with pleasure.
