Caramelised Onion Dip: The Story behind the Recipe
It’s no secret that every recipe is unique. And this one is not an exception. The dip was originally a simple snack for the home in the mid-20th century. But it soon became popular at many parties, especially in America. It is believed that the popular 1950s recipe combining dried onion soup mix and sour cream was the reason for the growth of onion dip. With time, the caramelised onion became more prominent, giving rise to the version we are familiar with today.
Why are caramelised onions so delicious?
What is so special about an onion? The natural sugars in onions are destroyed when they’re cooked at low temperatures, resulting in a rich golden colour. The Maillard reactions are nature’s secret to unlocking flavour.
For the same reasons that roasted bread, seared beef, and toasted coffee are so delicious. It is the same reaction that balances onions’ natural sweetness with their natural sharpness.
