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 flavor, and its syrup sets firm when cooked to hard ball stage.
- Egg whites
- Whipped into the hot syrup to add airy structure and body to the candy.
- Walnuts
- Add crunch and nutty flavor throughout the candy.
- Milk
- Adds richness and softness to the sugar syrup, rounding its flavor.
The step that matters
Boiling the syrup to hard ball stage. Sugar syrup must reach the hard ball stage in cold water for the candy to set firm. Underheating leaves it soft and sticky, while overheating makes it brittle or grainy.
