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.
- Sugar
- Adds sweetness and helps the candy set firm as the mixture thickens.
- Baking soda
- Reacts with the acidic vinegar to release gas, lightening the candy's texture.
- Vinegar
- Acidity reacts with the baking soda and helps soften the sugar crystals.
The step that matters
Boil while stirring often. Molasses and sugar scorch easily on direct heat, and a dark, thick syrup can burn before it reaches the right stage. Frequent stirring spreads heat evenly and keeps the bottom from catching.
