Homemade Sweetened Condensed Milk

I have used condensed milk all my life. There was always a can of condensed milk in the cupboard when I was growing up. I have fond memories of my dad making us thick slices of warm baguettes with creamy condensed milk drizzled on top. While we ate, my dad would make himself chicory coffee with a big dollop of condensed milk. As an adult and a mom, I am now the parent who puts condensed milk in her mug of coffee.

Whenever I travel to Southeast Asia, the first thing I do is visit a cafe to get a strong iced coffee with sweetened condensed milk. According to my parents, condensed milk was popular when they were growing up in Cambodia, primarily because of the lack of available refrigeration for fresh milk and also the fact that most cows were used for manual labor, not milk. Interestingly, across Asia, condensed milk diluted with water was fed to babies and used as creamer in coffee.  

What Is Condensed Milk?

Condensed milk is milk that has been condensed by means of heat. As the milk cooks, the majority of the water evaporates, and the texture of the milk becomes gooey.  And it becomes sweeter; another very important ingredient in condensed milk is sugar. (If there was no sugar added it would be evaporated milk.) Sugar is added not only for sweetness; it prolongs shelf life. Typical microorganisms are not able to grow and multiply due to the high content of sugar in condensed milk, allowing it to last longer.  

History of Condensed Milk

In the 1850s, there was little available refrigeration for dairy products. An inventor named Gail Borden boarded a ship that carried farm animals on a journey from Europe to the US. The ship was carrying livestock to provide food for passengers and the crew. During that trip, the cows became sick and died. Children on the ship drank milk from the sick cows and they became very ill. Through this experience, Borden became passionate about finding a way to preserve milk for safe consumption. 

Inspired by the Shaker community, Borden tried to use a vacuum evaporator, a device that reduces the interior pressure of the evaporation chamber below atmospheric pressure. In doing so it eliminates the requirement of heat in the condensation process. Unfortunately, his first two attempts using this technology failed. Then, Borden found a successful technique and in 1858 opened the New York Condensed Milk Company that manufactured and marketed the iconic Eagle Brand that established the industry.

Homemade Is Better

Homemade condensed milk is not only cheaper, but it tastes more delicious, as making it requires less heat and sugar, allowing the flavor of the milk to come through. Also, canned condensed milk can contain preservatives or additives, while homemade condensed milk only takes two ingredients to make. Finally, you can personalize your homemade condensed milk by adding different spices and extracts such as cinnamon, vanilla, chocolate, or nutmeg. 

How to Store Homemade Condensed Milk 

Before storing condensed milk, cool it completely, and transfer it to an airtight container, such as a jar with a tight-fitting lid. Label and date; it will last for 1 month in the refrigerator. 

The condensed milk will become thicker as it cools. To make it pourable, you can microwave the condensed milk in 10-second intervals until it has reached the desired consistency when you want to use it again.
