Ingredients
- 1 cup (200 g) granulated sugar
- ¼ cup (60 ml) water
- ½ cup (120 ml) heavy cream, warmed
- ¼ cup (60 g) unsalted butter, cubed
- 2 Tbsp dark rum (aged 12‑18 months)
- ½ tsp flaky sea‑salt (plus extra for garnish)
- 1 tsp pure vanilla extract (optional)
Step‑by‑Step Instructions
- Prep the workspace. Gather a medium‑sized heavy‑bottom saucepan, a heat‑proof silicone spatula, and a small bowl of warm heavy cream.
- Combine sugar and water. Add the granulated sugar and water to the saucepan. Stir just enough to moisten the sugar; avoid over‑mixing to prevent crystallization.
- Heat to caramelize. Place the saucepan over medium‑high heat. Watch as the mixture bubbles and turns a golden amber. Swirl the pan gently—do not stir—until the sugar fully dissolves and reaches a deep amber color (about 5‑6 minutes).
- Incorporate butter. Remove the pan from heat and immediately whisk in the cubed butter. The mixture will bubble vigorously; continue whisking until the butter is fully melted and the sauce is smooth.
- Add the warm cream. Slowly pour the warmed heavy cream into the caramel while whisking constantly. The sauce will expand; keep whisking to maintain a smooth texture.
- Stir in rum and salt. Return the pan to low heat and stir in the dark rum and flaky sea‑salt. Allow the mixture to simmer for another 2‑3 minutes, letting the alcohol evaporate slightly and the flavors meld.
- Optional vanilla boost. If you love a hint of vanilla, add the vanilla extract now and whisk for an additional 30 seconds.
- Test consistency. Drop a spoonful of sauce onto a chilled plate. If it thickens but remains pourable, it’s ready. If it’s too thin, simmer a minute longer; if too thick, whisk in a splash of cream.
- Cool slightly. Transfer the sauce to a heat‑proof jar. It will continue to thicken as it cools to room temperature.
- Serve & enjoy. Drizzle over vanilla ice‑cream, a warm brownie, or stir into a classic Old Fashioned for an elevated cocktail experience.
Pro Tips & Tricks
- Use a heavy‑bottom pan. It distributes heat evenly, preventing hot spots that can burn the sugar.
- Warm the cream. Cold cream can cause the caramel to seize, creating lumps.
- Don’t stir the sugar water. Swirling ensures even caramelization without crystallization.
- Choose quality rum. A dark rum with caramel notes enhances the sauce’s depth without overwhelming sweetness.
- Finish with flaky sea‑salt. Sprinkle a pinch on top of the finished sauce for an extra pop of texture and flavor.
Variations & Substitutions
Spiced Rum Version
Swap the dark rum for a spiced rum and add a pinch of ground cinnamon or nutmeg for a warm holiday twist.
Vegan Alternative
Replace butter with coconut oil and use full‑fat coconut milk instead of heavy cream. The sauce will have a subtle coconut note.
Chocolate Infusion
Stir in 2 Tbsp of high‑quality cocoa powder after adding the rum for a rich chocolate‑caramel hybrid.
Fruit‑Infused Drizzle
Blend in a tablespoon of pureed roasted pineapple or mango for a tropical caramel sauce that pairs beautifully with rum‑based cocktails.
Storage Tips
Transfer the cooled sauce to an airtight glass jar. Store in the refrigerator for up to 2 weeks. To re‑heat, gently microwave in 15‑second intervals, stirring between each, or warm over low heat on the stovetop. If the sauce thickens too much, whisk in a splash of milk or cream until the desired consistency returns.
