Why it works: Red currant and sugar are a kitchen classic. They rank in the top 26% of all ingredient pairs, and cooks put them together in 1,156 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Red Currant Jam
Ingredients
Directions
Prepare the currants
Remove the stalks from the currants.
Place the currants in a cane sieve over a preserving pan and rub them through with your hands.
Make the jam
Add the sugar to the pan and set it over a brisk fire.
Boil for about 20 minutes.
To test if it's done, drop a little on a cold plate; if it sets in a minute or two, it's ready.
If not, continue boiling slowly until it sets.
Pot and store
Pour the jam into pots or jars and cover once cool.

The flavor team
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
- Red currants
- Provide the fruit, pectin and acidity that give the jam its flavour and ability to set.
- Sugar
- Sweetens the jam and helps it set by binding water and concentrating the fruit.
The step that matters
Testing for the set. Pectin and sugar only gel at the right concentration, so jam boiled too briefly stays runny while overboiling can make it stiff and dull. A cold-plate test shows whether it has reached setting point.
