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 ↓

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
- Isinglass
- Sets the liquid into a firm, tender jelly as it cools.
- Lump sugar
- Sweetens the juice and helps form the thick syrup.
- Orange and lemon juice
- Supplies the acidity and bright flavour of the jelly.
The step that matters
Boil the juice, sugar and water until it thickens. The syrup must be reduced enough to concentrate its sugar and flavour. If it is under-boiled, the jelly will be weak in taste and may not set as firmly once combined with the isinglass.
