- Peanuts
- Add crunch and a roasted, nutty flavor to the set candy.
The step that matters
Cook gently without stirring until the cold-water test hardens quickly. Sugar syrup must reach the correct concentration to set brittle when cool. Undercooked syrup stays sticky, while overcooked syrup turns bitter or burnt. Stirring can trigger crystallization, leaving a grainy texture.
