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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatine
- Forms a gel network that sets the liquid into a firm, sliceable jelly.
- Sugar
- Adds sweetness and balances the sharpness of the citrus juices.
- Lemon juice
- Adds acidity that brightens the flavour and sharpens the sweetness.
- Orange juice
- Provides the main orange flavour and aroma of the jelly.
The step that matters
Stir the sugar and boiling water until fully dissolved. Undissolved sugar or gelatine grains leave gritty spots and weak patches, so the jelly will not set evenly or look clear.
