Dulce de leche – Literally, a milk-based caramel sauce or candy

Dulce de leche is a popular South American caramel sauce composed of only two ingredients: milk and sugar. In fact, the name literally translates to “milk jam” (side note: it is pronounced as “dul-say,” as opposed to “dul-che” — you’ll gain some cool points for this). According to Alton Brown, dulce de leche most likely evolved as a way to preserve milk in the pre-refrigerator era. Though its flavor is complex and layered, dulce de leche is deceptively simple to make.

So how does combining milk, sugar, and heat turn into something as lucious and spoonable as dulce de leche? The answer lies in science — more specifically, chemistry. As all you lactose-intolerant folk out there know, milk has plenty of lactose. Lactose is a sugar, but is not as sweet as sucrose or glucose (which are found in typical table sugar, fruits, and sugared fruits). As dulce de leche is essentially caramelized milk, it is a more complex, less saccharine caramel than its more traditional cousin – caramel.
