Why it works: Orange and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 10,634 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓
Seville Orange Jelly
Ingredients
Directions
Prepare the juice
Squeeze the juice from the Seville oranges and filter the orange juice through blotting paper.
Make the syrup
Dissolve one pound of sugar in ½ cup of water.
Add the rinds and juice of three lemons and the whites of five eggs to the sugar mixture, and whisk until the sugar is dissolved.
Add the filtered orange juice to the mixture.
Cook and clarify
Place the mixture on the fire, whisking until it boils, then remove from heat.
Strain through a jelly bag until clear.
Flavor with cherry wine or your choice of flavoring.
Set
Pour into molds or glasses.
Set in ice.

Sugar and lemon barely smell alike, yet cooks put them together in 53,532 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
- Seville oranges
- Provide the main juice, giving the jelly its tart, bitter-citrus flavor and aroma.
- Sugar
- Adds sweetness and, with the cooked juice, helps the mixture set into a firm jelly.
- Lemon juice
- Adds acidity that brightens the flavor and supports the jelly's setting.
- Lemon rinds
- Add aromatic oils and natural pectin that help the jelly set.
- Egg whites
- Coagulate when heated and trap cloudy particles, so straining leaves the jelly clear.
The step that matters
Strain through a jelly bag until clear. Egg white proteins coagulate as the mixture boils and trap cloudy particles. Straining slowly through the bag removes them, so rushing this step leaves the jelly cloudy.
Swap the cherry
How well each one fits the dish's main ingredients (orange, sugar, lemon, egg):
- Vanillafits better
- Limefits better
- Blueberryfits about as well
- Cherrythe original
Fit is the average pairing score against orange, sugar, lemon, egg. Candidates are from the same food group and used in at least 100 recipes.
