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
Soak the gelatine in 2 cups of water.
Squeeze the juice from the oranges and lemons into a bowl.
Grate the zest of one lemon into the bowl.
Make the jelly
Mix the sugar with the soaked gelatine.
Stir in the orange juice and pour in 3 pints of boiling water, stirring constantly.
Once the gelatine is fully dissolved, strain the mixture through a cloth into molds or bowls that have been wet with cold water.
Set
Set aside to harden for 3 to 4 hours.

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, sliceable jelly as it cools.
- Sugar
- Adds sweetness and balances the sharpness of the citrus juice.
- Oranges
- Provide the main juice and flavour of the jelly.
- Lemons
- Add acidity and bright citrus aroma from juice and zest.
The step that matters
Dissolving the gelatine fully. Gelatine only sets properly when it is completely dissolved in hot liquid. Undissolved granules leave weak spots and grainy texture, so stir until no granules remain before straining and cooling.
