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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Isinglass
- Sets the liquid into a firm jelly as it cools.
- China orange juice
- Provides the main orange flavour and most of the liquid body of the jelly.
- Sugar
- Adds sweetness and balances the tartness of the juice.
- Lemon juice
- Adds acidity to sharpen the flavour of the jelly.
The step that matters
Skim the mixture clean without boiling. Boiling would cloud the jelly and can weaken its setting power, so the mixture should be kept just below a boil while skimming off foam and impurities for a clear, firm result.
