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.
