In a 3-quart heavy-bottomed saucepan, combine the sugar and water.
Stir lightly to ensure the sugar is spread in an even layer.
Heat the Mixture:
Place the saucepan over medium heat.
Allow the sugar to dissolve into a clear, bubbling liquid; this will take about 3-4 minutes.
Once bubbling, stop stirring. Gently swirl the pan and brush down the sides to prevent sugar crystals from forming.
Caramelize the Sugar:
Continue to heat until the sugar mixture thickens and turns a deep amber color, akin to honey, about 8-12 minutes.
Monitor closely to avoid burning.
Add Butter:
Carefully add the butter to the pan.
Whisk continuously until the butter is fully melted and integrated. Note: The caramel will bubble vigorously.
Incorporate Cream:
Remove the pan from heat.
Gradually pour in the heavy cream, whisking constantly until smooth and fully combined.
Final Flavoring:
Stir in the vanilla extract and a pinch of salt.
Cooling:
Let the caramel cool in the pan for 10 minutes.
Transfer the caramel to a glass jar with a lid and allow to cool completely. It will thicken as it cools.
Storage:
Store your caramel sauce in the refrigerator, sealed tightly, for up to 3 weeks, or freeze it for up to 2 months. The caramel will solidify when cold; reheat in the microwave to achieve the desired consistency.
