How To Make Pineapple Rum Sauce
Here’s an overview of how to make this pineapple rum sauce.
(Scroll below to the printable recipe card for complete details and watch the video.)
- Simmer. Bring the pineapple juice and brown sugar to a gentle simmer, stirring frequently, until the sugar is completely dissolved.
- Thicken. Add the butter, cinnamon, and salt. Continue cooking until reduced and thickened.
- Add the rum. Stir in the rum and cook for an additional minute.
Tips for Success
- Stir frequently. You’ll want to stir the mixture frequently as the sugar is dissolving to ensure that it doesn’t burn.
- Don’t increase the heat. Similarly, you want just a gentle bubble – not a full boil. Having the heat too high can cause the rum sauce to burn.
- Remove from heat after the rum. Cook the mixture with the rum for just an additional minute or so. Longer than that will cause the rum to cook off completely and you will lose some flavor.
