Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Forms the sweet candy base that hardens into a brittle, glassy texture as it cooks.
- Vinegar
- Acidity that helps prevent sugar from crystallizing, keeping the candy smooth.
- Baking soda
- Reacts with the acid to create gas bubbles that lighten the candy and make it pull white.
- Butter
- Adds fat for a softer bite and richer flavor in the finished candy.
The step that matters
Boiling without stirring. Stirring during boiling can trigger sugar crystals to form, making the candy grainy instead of smooth. Checking for a crisp snap in cold water shows when the sugar has reached the right concentration.
