Ingredients

  • 1/2 cup light corn syrup
  • 1/3 cup brown sugar, firmly packed
  • 1/3 cup butter
  • 3 tablespoons light rum

Instructions

  1. Combine corn syrup, brown sugar, and butter in a heavy saucepan; bring to a boil, stirring constantly.
  2. Cook over medium heat until the mixture reaches soft ball stage (234°F).
  3. Remove from heat and let cool for 5 minutes.
  4. Add rum and half and half, stirring well.
  5. Serve warm over ice cream or pound cake.

Tips & Substitutions

For a smoother sauce, ensure the butter is fully melted before adding the other ingredients. If you don’t have light rum, vanilla extract can be a great substitute for a non-alcoholic version. Stir constantly to prevent burning, and consider using a candy thermometer for precision when checking the soft ball stage.

Frequently Asked Questions

Can I make this sauce ahead of time?

Yes, you can prepare the butterscotch sauce in advance. Just follow the recipe, let it cool, and store it in the fridge. Reheat it before serving to ensure it's warm and pourable.

What can I use instead of light corn syrup?

If you don’t have light corn syrup, you can substitute with an equal amount of honey or maple syrup. The flavor will vary slightly, but it will still create a delicious sauce.

Is there a way to make this sauce thicker?

To thicken the sauce, cook it a little longer until it reaches a higher temperature, around 240°F. Keep in mind that it will thicken more as it cools, so monitor it closely.
