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 ↓
Lemon Jelly with Orange Sections
Ingredients
Directions
Make the jelly
Soak the gelatine in cold water for 1 hour.
Add lemon juice and sugar to the soaked gelatine.
Pour in boiling water and stir until dissolved.
Set and layer
Wet a pie dish with cold water.
Pour a small bowlful of jelly into the wet pie dish.
Divide the orange into sections and remove the seeds from the orange sections.
Place the orange sections in half of the jelly.
Cut and serve
Once the jelly is cold, cut it into square pieces.
Arrange the square pieces on a plate.
Cut the remaining jelly into small cubes.
Pile the cubes on top.

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 that holds its shape when cut.
- Sugar
- Adds sweetness and contributes to the jelly's body and flavour.
- Lemon juice
- Adds acidity that brightens the flavour and balances the sweetness.
- Orange
- Adds fresh citrus flavour and pieces of fruit set within the jelly.
The step that matters
Soak the gelatine fully before adding hot water. Gelatine must hydrate in cold water first so its proteins dissolve evenly in the boiling water. Undissolved granules leave gritty spots and weaken the set.
