Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Molasses
- Provides the main body, dark color, and deep sweetness of the candy.
- Granulated sugar
- Adds sweetness and helps the mixture reach a hard, brittle set when boiled.
- Vinegar
- Adds acidity that helps prevent sugar crystallization and keeps the candy smooth.
- Baking soda
- Reacts with the hot acidic syrup to create gas bubbles that lighten the candy's texture.
The step that matters
Boil until it hardens in water. Sugar syrup must reach the hard-crack stage to set brittle rather than sticky. Undercooking leaves the candy soft and tacky, while overcooking can scorch the molasses and taste bitter.
