Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Brown sugar
- Provides sweetness and molasses flavor, and as it boils it thickens into the candy base.
- Vinegar
- Adds acidity that helps keep the boiled sugar smooth and reduces crystallization.
- Walnut kernels
- Add crunchy texture and nutty flavor to the candy.
The step that matters
Boil without stirring. Stirring a boiling sugar syrup can encourage sugar crystals to form, leaving the candy grainy instead of smooth. Letting it boil undisturbed lets the syrup reach the concentration needed to set.
