Why it works: Lemon and orange 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
Soften the gelatine in cold water.
Dissolve the gelatine with the boiling water.
Add the sugar, lemon juice, and orange juice.
Strain the mixture through a cheesecloth.
Garnish and serve
If desired, garnish the mould with orange slices held in place with a little jelly.
Unmould and surround with whipped cream, sprinkled with candied orange peel.
Alternatively, serve the jelly in an orange basket made from the skin, topped with whipped cream.

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 tartness of the citrus juices.
- Lemon juice
- Adds acidity that brightens the flavour and sharpens the orange taste.
- Orange juice
- Provides the main liquid and orange flavour of the jelly.
The step that matters
Soften the gelatine in cold water. Gelatine must first hydrate in cold liquid so its proteins can dissolve evenly in hot water. Adding it dry or to hot liquid can leave lumps and weaken the set.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
