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 Jelly
Ingredients
Directions
Extract the juice
Place the currants in a saucepan with a little water and simmer for about 30 minutes until all the juice is extracted.
Strain through a jelly bag or fine cloth into a preserving pan.
Make the jelly
Add 2 pounds of sugar for each 4 cups of juice.
Boil slowly for about 30 minutes.
Skim well.
To test if the jelly is set, place a small amount on a cold plate.
Jar and store
Pour into small dry jars, seal, and store in a cool, dry place.

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 juice and natural pectin that set the jelly.
- Preserving sugar
- Sweetens the jelly and helps it set and keep well.
The step that matters
Testing for set. Jelly sets when pectin, acid and sugar reach the right balance at the right concentration. Boiling too briefly leaves it runny, while overcooking can make it stiff. A cold plate test shows whether it will gel as it cools.
