 Coffee Caramel Sauce:

• Pour sugar into a saucepan and melt it slowly over medium-low heat without adding water. Stir it constantly with a wooden spoon (or rubber one) until it starts clumping together. At this point, stir in espresso (about three tablespoons of strong coffee). Continue mixing, as it can burn very quickly. Once the sugar melts completely, you will see it bubbling and a deep amber color - stir in the butter cubes. Keep mixing until the butter has melted. Add a pinch of salt at the end and ​​cook until it turns into a deep brown caramel sauce. It will take you about 3-5 minutes.
• Switch off the stove and leave the caramel to cool for 5-10 minutes. Then pour it over the cake.
