A jar of salted caramel rum sauce.

Caramel Rum Sauce


Ingredients

  • 3 cups heavy cream
  • 2 cups granulated sugar
  • 3/4 cup corn syrup
  • 2 tsp kosher salt
  • 1 tsp pure vanilla extract
  • 1/2 cup Rum – or more! (I usually use dark rum, but light works too)

Instructions

  1. In a medium, heavy bottom saucepan, heat the cream to almost boiling – bubbles will start to appear around the side of the pan and the surface will get a bit “rumbly”. Turn down the heat to low and keep warm.
  2. In a large heavy bottom saucepan, add 1 cup of the sugar, the corn syrup, and salt. Stir to moisten the sugar and then cook without stirring over medium high heat just until the sugar starts to turn golden. If you notice that the syrup is quickly turning brown in one spot, but the rest is not browning at all, grip both sides of the pan and swirl the syrup around to distribute the caramelizing sugar before it burns. Cook until all the syrup is a light golden color – somewhere between the color of straw and milk chocolate.
  3. Turn the heat down to medium-low and add the remaining cup of sugar in three additions, stirring constantly, allowing each addition to melt before adding more. The sauce will continue to darken in color. Cook, stirring constantly, until the sauce is a deep amber color. Watch the heat in order to prevent the sugar from burning. The sauce should steadily darken in color, but if it begins to smoke at all, immediately remove it from the heat, stirring vigorously, and lower the burner heat. Return the pan to the burner and continue. If the sugar does turn black and burn, there’s no other option except to start over.
  4. Turn the heat up to medium and add the warm cream in three additions. The cream will cause the syrup to bubble up significantly – stir constantly and be very careful to not let the hot steam burn you. Simmer for a minute or two between each addition of cream to reduce slightly. Once all the cream has been added, continue to cook, stirring constantly, until it forms a thick syrup. If you draw your finger across the back of your spoon, it will hold the line.
  5. Remove from the heat and stir in the vanilla and rum. Taste and add more rum if you like. Pour into a container and let cool completely. The caramel sauce will keep in the refrigerator for up to 6 months.
