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 Mould
Ingredients
Directions
Prepare the liquid
Combine the juices of the oranges and lemon.
Add enough water to the fruit juices to make 1 quart of liquid.
Make the mould
In a saucepan, heat 1½ pints of the liquid with the sugar until near boiling.
In a bowl, mix the remaining liquid with the cornflour and beaten eggs until smooth.
Stir the cornflour and egg mixture into the boiling liquid.
Continue stirring over gentle heat for 5 minutes until thickened.
Pour into a wetted mould and let it cool.
Once set, turn out and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the mixture into a firm, sliceable structure as they thicken with heat.
- Cornflour
- Thickens the juice into a smooth, wobbly set when heated and cooled.
- Sugar
- Sweetens the tart citrus juice and balances its acidity.
- Orange juice
- Provides the main liquid, flavour and aroma of the mould.
The step that matters
Stirring the cornflour and egg mixture into the boiling liquid. Adding the egg and cornflour mixture to very hot liquid while stirring keeps it smooth; if it is added too quickly or not stirred, the eggs can scramble into lumps and the starch may not thicken evenly.
Swap the orange
How well each one fits the dish's main ingredients (lemon, sugar, egg):
- Orangethe original
- Vanillafits about as well
- Limefits less well
- Raisinfits less well
Fit is the average pairing score against lemon, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
