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 fruit
Ensure the red currants are thoroughly ripe.
Rub the currants through a matted sieve to remove stalks.
Combine the mashed currants with the sugar in a pot.
Cook the jam
Stir the mixture well from the bottom while boiling.
Boil over a brisk heat for about 20 minutes if using 1 pound of currants.
To test for doneness, drop a little jam on a plate and cool it; if it sets, it's done.
If not set, boil a little longer.
Pot and store
Pour the jam into pots and cover with paper soaked in brandy when cool.
Seal with paper and store in a dry room.

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, acidity and pectin that give the jam its flavour and body.
- Sugar
- Sweetens the jam and, with boiling, helps it thicken and set as it cooks down.
The step that matters
Testing for set. Jam sets as its sugar and pectin concentrate during boiling and cooling. Stopping too early leaves it runny, while overcooking can make it stiff, so testing a cooled spoonful on a plate shows when it is ready.
