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 ↓
Currant Jelly
Ingredients
Directions
Extract the juice
Fill a preserving pan with fresh red currants and add ½ cup water.
Mash the currants as they boil for 30-45 minutes until juice is extracted.
Strain the mixture through a jelly bag.
Cook the jelly
Measure 1 cup of juice and 1 cup of sugar, then return to the pan and boil for 7 minutes.
Pour and set
Pour the jelly into tumblers.
Heat the sugar in a bowl in the oven before adding.
Test the jelly by dipping a silver spoon; if it jellies, it's done.

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
- Fresh red currants
- Provide the fruit flavour and the natural pectin and acid that let the juice set.
- Sugar
- Sweetens the juice and helps it set into a firm gel.
The step that matters
Test the jelly with a cold silver spoon. Sugar, pectin and acid must reach the right concentration to gel. Boiling too briefly leaves the jelly runny, while boiling too long can make it stiff and cloudy, so the spoon test shows when it is ready.
