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
Prepare the juice
Gather red currants in fine weather.
Remove them from the stalks.
Place the currants in a jar.
Set the jar in a saucepan of boiling water. Simmer gently until the juice is well drawn from the currants.
Strain the juice through a fine cloth jelly bag without squeezing too much.
Measure the juice.
Make the jelly
Add ¾ pound of loaf sugar for each pint.
Put the juice and sugar in a preserving pan over the fire. Stir constantly.
Remove any scum that rises with a wooden or silver spoon.
Boil for 20 to 30 minutes.
Test for firmness by placing a little on a plate.
Remove from heat.
Jar and store
Pour into small jars.
Cover each jar with oiled paper. Cover with tissue paper brushed with egg white.
Label the jars with the year made. Store in a 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 juice and natural pectin that set the jelly.
- Loaf sugar
- Sweetens the juice and helps it set into a firm gel.
The step that matters
Testing for firmness. Jelly sets as the boiling juice concentrates and its pectin and sugar reach the gel point. Boiling too briefly leaves it runny, while overcooking can make it stiff or cloudy, so testing a cold dab on a plate shows when it is ready.
