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 ↓
Orange Jelly
Ingredients
Directions
Prepare
Grate the rind of the oranges and lemons.

Make the jelly
Add the juice to the sugar and water, then boil until it thickens.

Combine the syrup with the isinglass jelly and boil once more.
Strain the mixture and let it settle before pouring into a mold.

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 jelly as it cools.
- Sugar
- Adds sweetness and body to the syrup.
- Seville oranges
- Juice gives sharp acidity, and the grated rind adds bitter aroma.
- Lemons
- Juice adds acidity that brightens the flavour.
The step that matters
Combining the syrup with the isinglass jelly and boiling once more. Isinglass is a protein-based gelling agent, and prolonged boiling can weaken its setting power, so the mixture should not be boiled longer than needed.
