Decadent Salted Caramel Sauce

Combine sugar and water in a compact cooking vessel, stirring softly to merge the ingredients. Warm over a moderate-low thermal setting until tiny bubbles start to emerge on the sides of the pan. Elevate the heat to a high level and bring to a rolling boil until the sugar transforms into a deep amber hue, taking approximately 5 to 8 minutes. Take the pan off the heat source and carefully blend in heavy cream using a whisking motion. Introduce butter and salt into the mixture, stirring until they are fully incorporated. Pour the caramel mixture into a clear glass container and allow it to cool down gradually.
