Instructions

1. In a small saucepan over medium-high heat whisk together sugar and water and bring to a boil. Cook until sugar has dissolved, about 1 minute.
2. Reduce heat to a simmer. Add in butter and whisk until combined. Simmer until the mixture turns a deep amber color, about 5 minutes. 
3. Remove from heat and carefully whisk in the cream (it will bubble up ferociously after you add it!). Whisk until well combined. Whisk in salt. 
4. Pour caramel into a heatproof jar. Allow it to cool a few minutes before using.
