Why it works: Lemon and orange 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 ↓
Lemon Jelly
Ingredients
Directions
Prepare
Juice the lemons and strain the juice to remove seeds.
Prepare the oranges by peeling them carefully to remove all the white skin.
Make and set the jelly
In a saucepan, combine the lemon juice, sugar, and water.
Heat until the sugar dissolves and the mixture thickens slightly.
Pour a little lemon jelly into a mold and let it harden.
Once hardened, place the prepared oranges in the mold and pour more liquid jelly over them to cover.
Keep any reserved jelly in a warm place until needed.

Lemon and sugar 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
- Lemons
- Lemon juice supplies the sharp acidity and the flavour base of the jelly.
- Sugar
- Sugar adds sweetness that balances the lemon's acidity and helps the jelly set.
- Oranges
- Orange segments add sweetness, texture and fruit pieces suspended within the set jelly.
The step that matters
Peeling the oranges. Leftover white pith tastes bitter and can cloud the jelly, so every trace should be removed before the fruit goes into the mold.
