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
Make the jelly
In a saucepan, combine boiling water, gelatin, sugar, and orange rinds. Bring to a boil.
Remove from heat and let stand for 10 minutes until gelatin is dissolved.
In a basin, combine orange juice and lemon juice. Strain the gelatin mixture into the juices.
Set and turn out
Pour the mixture into small dariole moulds rinsed with cold water.
Once firm, dip the moulds in warm water and turn the jelly onto a cold dish.

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 jelly that holds its shape when turned out.
- Sugar
- Adds sweetness and balances the sharpness of the citrus juices.
- Orange juice
- Provides the main orange flavour and most of the liquid in the jelly.
- Lemon juice
- Adds acidity that brightens the flavour and sharpens the orange taste.
The step that matters
Dissolving the gelatine fully before adding the juices. Gelatine only sets when it is completely dissolved and evenly distributed. Undissolved granules leave weak or cloudy patches, and the mixture must be cooled slightly so the juice's acidity and flavour are not dulled by heat.
