Why it works: Black currant and sugar work together. They rank in the top 22% of all ingredient pairs, and cooks put them together in 393 recipes. Both carry 1-penten-3-one, which smells fish, pungent. The science ↓

What each ingredient does
- Ripe black currants
- Provide the fruit juice that forms the base and gives the lozenges their flavour and colour.
- Brown sugar
- Adds sweetness and body, and helps the juice thicken into a firm, chewable mass as it boils.
- Isinglass
- A gelatin-like protein that sets the cooked juice into a firm, sliceable lozenge when dried.
The step that matters
Boil for 45 minutes. The juice must be boiled long enough for the sugar to concentrate and the mixture to thicken. Too short a boil leaves it too wet to dry into firm lozenges, while overcooking can scorch the sugar and darken the flavour.
