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 ↓
Cranberry, Grape, and Currant Jelly
Ingredients
Directions
Prepare the fruit
Wash and drain the fruit until nearly dry.
Place the fruit in an earthen jar and set it in a kettle of hot water to boil, ensuring no water enters the jar.
Once the fruit breaks, pour it into a flannel bag and let it drain into a deep dish without squeezing.
Make the syrup
For each pint of juice, add 1 ½ cups of white sugar.
For each quart of syrup, add the beaten egg white.
Boil the syrup gently, skimming off any scum that rises.
Boil for 15 to 20 minutes, then test by dropping a bit into cold water; if it sinks, it's done.
Seal and set
Pour into tumblers and seal with white paper smeared with egg white, then place in the sun to set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fresh cranberries, grapes, or currants
- Provide the fruit flavor and natural pectin that help the juice set into jelly.
- White sugar
- Sweetens the juice and helps it thicken and set as it boils down.
- Egg white
- Gives the syrup a clarifying effect, lifting scum so the jelly looks clear.
The step that matters
Boil the syrup gently and test for doneness. Gentle boiling keeps the syrup from scorching and clouding, while the cold-water test shows whether enough water has evaporated for the sugar and pectin to gel.
Swap the grape
How well each one fits the dish's main ingredients (sugar, egg):
- Vanillafits better
- Raisinfits better
- Lemonfits better
- Grapethe original
Fit is the average pairing score against sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
