Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Horehound leaves
- Supply the bitter, herbal flavour that the steeped tea carries into the candy.
- Coffee sugar
- Forms the bulk of the candy and sets into a hard, glassy mass as it cools.
- Vinegar
- Adds a little acidity that helps keep the sugar from crystallising too readily.
The step that matters
Cooking until the mixture breaks when dropped in water. Hardness depends on how much water the sugar syrup has lost. Stopping too early leaves a sticky, soft candy, while cooking too long over-concentrates the sugar, making it brittle and prone to scorching and bitterness.
