To create a delicious caramel sauce, start by heating up some sugar in a small pan over medium heat. It's important to use a pan with a sturdy bottom to prevent any hot spots that could burn the caramel.
Keep stirring the sugar constantly as it melts to ensure even melting. Once all the sugar has dissolved, the syrup will begin to turn a light brown color.
Once the syrup is smooth and there are no sugar granules left, take the pan off the heat. Be cautious at this stage, as the next step involves pouring half a cup of water over the hot syrup. Pour the water slowly and from a safe distance, as it may cause the caramel to splatter.
After pouring the water over the syrup, you will notice that the caramel has hardened. Return the pan to the heat and continue stirring with a spatula until all the sugar has melted again.
Once the syrup has a rich, amber color and is completely smooth, you can remove it from the heat. Remember that the caramel should be a thin, light syrup to achieve the best results when making flan.
If you prefer a thicker caramel, you can boil the mixture for a few more minutes. However, keep in mind that the caramel will continue to thicken as it cools.
Transfer the caramel to a heat-safe container and allow it to cool to room temperature before using it to top your favorite desserts. Enjoy!
