In a heavy bottom sauce pan on medium heat, combine the sugar and water
Cook whisking frequently until sugar is dissolved and the mixture turns clear and bubbly, about 3-4 minutes
At this point stop whisking. Just gently swirl the sauce pan on the burner until the liquid turns amber, about 15 minutes. Do not walk away from the pot.
Once it has reached an amber color, remove from heat and carefully add the butter. The liquid may splatter.
Slowly add the cream, vanilla, and salt.
Place back on the warm burner for 2-3 minutes.
