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 ↓

Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Dissolve the soaked gelatine in 1 cup of boiling water.
Flavour and set
Stir in the sugar, orange juice, and lemon juice until well combined.
Pour the mixture into a mold and refrigerate until set.

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 gel as it cools.
- Sugar
- Adds sweetness and balances the tartness of the citrus juices.
- Orange juice
- Provides the main orange flavour and most of the liquid base.
- Lemon juice
- Adds acidity that brightens the flavour and cuts the sweetness.
The step that matters
Dissolve the soaked gelatine fully in the boiling water. Gelatine only sets when it is completely dissolved and evenly distributed. Any undissolved granules can leave soft or grainy spots, so stir until no particles remain before adding the other ingredients.
“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.
