Step 1

Mix together the cream, salt, and vanilla extract in a small bowl.  Set aside.

Step 2

Combine the sugar, water, and corn syrup in a medium saucepan.  Heat over medium heat, stirring frequently until the sugar has dissolved.

Step 3

Once the mixture starts to boil, stir occasionally and watch the color of the mixture closely - you're looking for a caramel colored liquid.  This can take anywhere from 8 to 12 minutes depending on your stove.

Step 4

As soon as the color has turned caramel, immediately remove from heat and mix in the heavy cream mixture.  Step back for a few seconds while the mixture bubbles and steams, and then start stirring.

Step 5

Once the caramel is smooth, pour into a glass container to cool.  Store in the refrigerator.  Microwave for 30 to 60 seconds to soften before serving.
