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 ↓
Black Currant Jam
Ingredients
Directions
Prepare
Weigh the black currants after removing the stalks.
Place the currants and sugar in a preserving pan.
Cook
Boil for 45 minutes, pressing the fruit with a wooden spoon to extract the juice.
Check if the jam sets by placing a small spoonful on a cold plate.
If it doesn't set, simmer a little longer.
Remove all scum and stir constantly to prevent burning.
Jar and store
Once done, pour the jam into jars and let it cool completely.
Cover jars with air-proof paper tied down or gummed.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

What each ingredient does
- Black currants
- Provide the fruit, flavour and natural pectin that the jam is built on.
- Loaf sugar
- Sweetens the jam and helps it set and keep well once cooked.
The step that matters
Testing for set. Setting depends on sugar, pectin and enough boiling to reach the gel point. Testing a spoonful on a cold plate shows whether it wrinkles when pushed. Stopping too early leaves runny jam, while cooking too long can make it stiff or scorch.
