Real-Deal Salted Butterscotch Sauce

By Sprig Originals ✓ · cooked up in Sprig

Butterscotch earns its name from dark brown sugar cooked hard with butter until it smells like toffee, not from caramel shortcuts. This version takes the sugar right to the edge of bitter, then pulls it back with hot cream, a splash of vanilla and enough flaky salt to make the whole thing taste less like candy and more like dessert. It pours warm, thickens to a spoon-coating gloss when cool, and keeps for weeks in the fridge.

Ingredients

• 1 cup heavy cream
• 6 tbsp unsalted butter, cut into cubes
• 1 1/4 cups packed dark brown sugar
• 2 tbsp light corn syrup
• 3 tbsp water
• 3/4 tsp fine sea salt

• 2 tsp vanilla extract
• 1 tbsp bourbon or dark rum (optional)
• 1/2 tsp flaky sea salt, plus more to taste
• 1 tsp fresh lemon juice

Instructions

1. Warm the cream in a small saucepan or in the microwave until steaming but not boiling, about 60–90 seconds in the microwave. Keep it hot and within reach — adding cold cream to hot sugar causes violent seizing and dangerous spattering.
2. In a 3-quart heavy-bottomed saucepan (use one much larger than you think you need; the sauce will triple in volume when it boils), combine the dark brown sugar, corn syrup, water, butter and fine sea salt. Set over medium heat and stir with a heatproof spatula just until the butter melts and the sugar looks wet and slurry-like.
3. Stop stirring and bring to a boil. Let it bubble hard for 5 to 7 minutes, swirling the pan occasionally rather than stirring, until the mixture darkens slightly, the bubbles get thicker and slower, and it smells distinctly of toffee. If you have a thermometer, you're aiming for 240–245°F.
4. Reduce the heat to medium-low and cook 1 to 2 minutes more, swirling constantly and watching closely. The sauce should smell nutty and just barely bitter at the edges — that's the butterscotch flavor. Pull it off the heat the moment you smell any sharp burnt note.
5. Off the heat, pour in the hot cream in a slow, steady stream while whisking. It will foam up aggressively; keep whisking until the foam subsides and the sauce is smooth and glossy.
6. Return to low heat and whisk for 1 minute to fully dissolve any sugar clinging to the pan. Remove from heat and whisk in the vanilla, bourbon if using, and the lemon juice — the acid sharpens the flavor and keeps the sauce from tasting flat.
7. Whisk in the flaky sea salt, then taste with a cool spoon (the sauce is scaldingly hot). Add more flaky salt a pinch at a time until the sweetness stops coating your tongue and the toffee flavor comes forward.
8. Let cool 15 minutes before pouring over ice cream, bread pudding, apple crisp or pancakes. It will be thin and pourable warm and thicken to a heavy, spoon-coating sauce at room temperature.
