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 Jelly
Ingredients
Directions
Prepare the fruit
Peel and cut up the oranges, removing seeds and thick white skin.
Place the oranges in a bowl and sprinkle with sugar.
Make the jelly
Soak the gelatine in ½ pint of cold water for 1 hour.
Add 1½ pints of boiling water to the soaked gelatine and sugar to taste.
Flavor with the juice of 2 lemons and stir until dissolved.
Pour the mixture over the oranges.
Set and serve
Transfer to a mold or break up when cool in a glass dish.

Sugar and lemon 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, wobbly jelly as it cools.
- Oranges
- Provide the main fruit flavor and pieces suspended in the jelly.
- Sugar
- Sweetens the jelly and balances the tartness of the citrus.
- Lemon juice
- Adds acidity that brightens the flavor of the orange.
The step that matters
Dissolving the soaked gelatine fully. Gelatine must be completely dissolved in hot liquid before setting; undissolved granules leave gritty or uneven patches and weak spots in the set jelly.
