Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Provides the main sweetness and the solid structure of the candy as it cooks and sets.
- Molasses
- Adds deep sweetness, rich flavor, darker color, and moisture to the finished candy.
- Vinegar
- Its acidity helps prevent the sugar from crystallizing into a grainy texture.
- Baking soda
- Reacts with the hot acidic mixture to release gas, making the candy lighter and more porous.
- Butter
- Adds fat that softens the candy's texture and gives it a richer mouthfeel.
The step that matters
Boil without stirring until it hardens in cold water. Stirring can trigger sugar crystals that make the candy grainy. Cooking to the hard stage, confirmed by the cold water test, sets the candy firm enough to pull or cut cleanly.
