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 ↓

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 as it cools.
- Sugar
- Sweetens the jelly and adds body to the set.
- Orange juice
- Provides the main flavour and liquid for the jelly.
- Lemon juice
- Adds acidity that brightens the orange flavour.
The step that matters
Soak the gelatine in cold water until soft. Gelatine must hydrate fully in cold water before heating, so its protein strands can unwind and later set evenly. Adding it dry or to hot liquid can leave lumps or weak setting.
