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 on a fine weather day and 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 extracted from the currants.
Strain the juice through a fine cloth jelly bag without squeezing too much to avoid muddy jelly.
Measure the juice. Add 2 ¼ cups of loaf sugar for every 4 cups of juice.
Make the jelly
In a preserving pan, combine the juice and sugar.
Stir the mixture over heat.
Remove any scum that rises using a wooden or silver spoon.
Boil for 20 to 30 minutes.
Test for firmness by placing a little jelly on a plate to cool.
Once firm, remove from heat and pour into small jars.
Seal the jars
Cover each jar with oiled paper. Then cover with tissue paper.

What each ingredient does
- Red currants
- Provide the juice that sets into the jelly, along with their natural pectin and tartness.
- Loaf sugar
- Sweetens the juice and helps the jelly set firm and hold its shape.
The step that matters
Testing for firmness. Boiling must reach the point where the juice sets when cool. Undercooked jelly stays runny, while overcooking makes it stiff and can make it cloudy or sugary.
