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 ↓
Oranges Jellied
Ingredients
Directions
Prepare the oranges
Cut a hole in the top of each orange, large enough for a small spoon, and carefully remove all the juice and pulp.
Make the jelly
Soak the lemon juice, orange pulp, sugar, gelatine, and cold water together for 30 minutes.
Place the mixture in a saucepan, pour in the boiling water, and stir until well dissolved.
Strain the mixture through a bag.
Fill and serve
Fill the orange skins with the mixture, put the tops back on, and set aside to cool and harden.
The next day, cut each orange in half with a sharp knife and serve one half to each person.

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
- Gelatine
- Sets the liquid into a firm jelly as it cools.
- Sugar
- Sweetens the jelly and balances the sharpness of the citrus.
- Lemon juice
- Adds acidity that brightens the flavour of the jelly.
- Oranges
- Serve as the edible shell and supply the main citrus flavour.
The step that matters
Dissolving the gelatine fully. Gelatine must be completely dissolved in hot liquid before straining and filling, otherwise undissolved granules will not set evenly and the jelly may come out grainy or weak.
