Why it works: Sugar and egg are a kitchen classic. They rank in the top 21% of all ingredient pairs, and cooks put them together in 122,807 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Black-Currant Jelly
Ingredients
Directions
Prepare the juice
Extract juice from the black currants.
For each pint of juice, add ½ lb of loaf sugar.
Make the jelly
In a preserving pan, combine juice and sugar over heat.
Stir continuously and remove any scum with a wooden or silver spoon.
Boil for 20 minutes to 1 hour until firm when cooled.
Jar and store
Pour into small jars and cover with oiled paper and tissue paper brushed with egg white.
Label jars with the year made and store in a dry place.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Black currants
- Provide the juice that gives the jelly its flavour, colour and natural pectin.
- Loaf sugar
- Sweetens the juice and helps the jelly set firm when boiled.
- Egg white
- Brushed on the tissue paper to help it seal to the jar.
The step that matters
Boiling until the jelly is firm. Boiling time varies, and the jelly sets only when enough water has evaporated and sugar and pectin reach the right concentration. Testing that it sets when cooled prevents a runny result.
Swap the black currant
How well each one fits the dish's main ingredients (sugar, egg):
- Vanillafits better
- Raisinfits better
- Lemonfits better
- Black currantthe original
Fit is the average pairing score against sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
