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 ↓
Redcurrant Jelly
Ingredients
Directions
Prepare the juice
Gather the currants on a fine weather day.
Remove them from the stalks.
Place the currants in a jar. Submerge the jar in a saucepan of boiling water.
Simmer gently until the juice is extracted from the currants.
Strain the juice through a jelly bag or fine cloth without squeezing too much.
Measure the juice.
Make the jelly
Add 3 lb of loaf sugar for every pint of juice.
Combine the juice and sugar in a preserving pan over heat.
Stir continuously.
Remove any scum that rises using a wooden or silver spoon.
Boil for 20 minutes to 1 hour.
Test for firmness by placing a little jelly on a plate to cool.

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 that gives the jelly its flavour and tartness.
- Loaf sugar
- Sweetens the jelly and, with the boiling, helps it set firm.
The step that matters
Boil for 20 minutes to 1 hour. Boiling concentrates the juice and sugar until the pectin and acid can form a gel. Too short a boil leaves the jelly runny, while overboiling can make it stiff and dull in flavour, so the cold plate test is used to check when it is ready.
