How long does sweetened condensed milk last in the fridge?

After opening, store the product at a temperature below 10ºC in a clean, dry container with a lid. So it will remain good for consumption for about 6 days.

Unopened cans of condensed milk should be stored at room temperature in a dry, dark area, such as the house pantry.

The closed container can be stored at room temperature for up to a year without losing its properties. It does not get spoiled beyond this period, although it does begin to lose its qualities. It may still be edible if maintained at the proper temperature and conditions.

Freezing condensed milk in standard household freezers is not suggested since the milk will separate from the fat, becoming watery and unfit for consumption. So do not put it in the freezer; if you do not use the entire can, leave it in the fridge and cook something different after six days so you do not waste it.

Always inspect the smell and sight; if you see anything unusual, such as a particular flavor or mold, do not consume it and discard it. Pay close attention to the can of condensed milk; if it is rusty, has a large dent, or is leaking, do not eat it since it might cause health concerns.

What are the origins of sweetened condensed milk and how it is produced?

Despite its name, sweetened condensed milk evaporates rather than condenses. It was given this name so that it would not be confused with evaporated milk, which is its unsweetened counterpart.

The first mention of a milk concentration process dates back to 1827 in France. However, it was not until 1853, with the American businessman Gail Borden Jr., that it became an industrial process. 

He wished to minimize the amount and lengthen the shelf life of milk, which frequently spoils on the route from the farm to the homes in the city (pasteurization would only be invented in the following decade, and the history of refrigerators was still in its infancy).

Condensed milk, on the other hand, gained popularity during the American Civil War (1861-1865), when it was approved as a ration for troops. The 395-gram cans were lightweight and simple to transport and store. 

They also included 1,300 calories, 80 grams of protein and fat, and more than 200 grams of carbohydrate, making them an excellent source of energy.

So, this is how sweetened condensed milk is produced:

  • The milk is centrifuged to eliminate impurities before being pasteurized at 75° C for 20 seconds.
  • It receives sugar, which aids in his preservation.
  • It is transferred to a vacuum evaporator set to temperatures ranging from 50° C to 70° C. It can not be boiled, so it does not change the color, flavor, and nutritional characteristics.
  • After cooling, it receives powdered lactose.

  • 1 cup (tea) of sugar
  • half a cup of hot water


  • 1 sweetened condensed milk (can or box) 395 g
  • 2 measures (from the can) of Whole Milk (790 ml)
  • 3 eggs

In a wide-bottomed pan, melt the sugar until golden. Add the hot water and stir with a spoon. Let it boil until the sugar clumps dissolve and the syrup thickens. Line a mold with a central hole (19 cm in diameter) with the syrup and set it aside.


In a blender, beat all the pudding ingredients and pour into the reserved form. Cover with aluminum foil and bake in a medium oven (180°C), in a bain-marie, for about 1 hour and 30 minutes. Once cooled, refrigerate for about 6 hours. Unmold and serve next.


  • It is essential that the pudding is prepared in a bain-marie so that it bakes in a slow and controlled way, to reach the ideal texture.
  • So that your pudding does not form holes, check that the oven temperature is set as indicated in the recipe. Place the pan in the oven on the upper rack, away from the flame.
