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
Prepare the juice
Remove the currants from the stalks using a fork.
Place the currants in a jar and set the jar in a saucepan of boiling water.
Simmer until the juice is extracted.
Strain the juice through a jelly bag or fine cloth.
Make the jelly
Combine the juice with sugar in a pot and stir until the sugar dissolves.
Boil the mixture for about 1 hour, skimming off any scum that rises.
Test for doneness by placing a little on a plate; if it firms up, it's ready.
Pour the jelly into small pots and cover.

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 natural pectin and acidity that give the jelly its body and tang.
- Sugar
- Sweetens the jelly and helps it set by binding water and concentrating the pectin.
The step that matters
Boiling the juice with sugar. Boiling must be long enough to evaporate water so the sugar and pectin concentrate and the jelly sets. Skimming removes scum that would otherwise cloud the jelly. Testing on a cold plate shows whether it has reached setting point.
