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
To prepare the mould, rinse it with boiling water, then cold water, and leave it wet.
Make the jelly
In a small saucepan, combine water, sugar, gelatine, and thinly cut orange rind.
Stir until the gelatine is dissolved, then bring to a boil.
Remove from heat and let sit for 10 minutes.
Add orange juice and lemon juice, then strain into a prepared mould.
Finish
Optionally, decorate the jelly with clear jelly and pistachio nuts or angelica.

Sugar and lemon 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, wobbly jelly when it cools.
- Sugar
- Sweetens the jelly and adds body to the set.
- Orange juice
- Provides the main orange flavour and liquid for the jelly.
- Orange rind
- Adds aromatic orange oils and a slightly bitter citrus note.
The step that matters
Straining in the orange juice after the boil. Orange juice and lemon juice are added after boiling and cooling so their fresh flavour and aroma are not dulled by heat. Gelatine needs to be fully dissolved before setting, so the mixture should be stirred until clear first.
