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 ↓
Currant Jelly
Ingredients
Directions
Make the jelly
Boil the currant juice and immediately remove it from the stove once it starts boiling.
Pour the jelly into glasses.
Cover the glasses
Cut wrapping papers larger than the tops of the glasses.
Dip a paper in the egg white and saturate it, then cover the glass, pressing down the edge.
Repeat with another paper and add it on top of the first.
Cover with a third paper to ensure the jelly is air-tight.
Tie the papers tightly around the glass.
Store
Store the jelly in a cool, dry place, not in a cellar.
Use 1 pound of sugar for every pound of juice, weighing the sugar.

Currant and sugar barely smell alike, yet cooks put them together in 12,256 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Currant juice
- Provides the fruit base and natural setting power that turns the liquid into jelly.
- Sugar
- Adds sweetness and helps the jelly set and keep well.
- Egg white
- Helps the paper stick to the glass, sealing the cover.
The step that matters
Remove the juice from the stove as soon as it boils. Boiling for too long can weaken the setting power of the fruit's natural pectin and darken the flavour, so the jelly may not firm up properly.
Swap the currant
How well each one fits the dish's main ingredients (sugar, egg):
- Vanillafits better
- Raisinfits better
- Lemonfits better
- 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.
