Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White sugar
- Forms the sweet base that hardens into the candy when boiled.
- Vinegar or lemon juice
- Acidity helps prevent the sugar from crystallising, keeping the candy smooth.
- Butter
- Adds fat for a richer flavour and a softer bite in the finished candy.
The step that matters
Do not stir. Stirring agitates the boiling sugar syrup and can trigger sugar crystals to form, making the candy grainy instead of smooth.
