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
Make the jelly base
In a saucepan, combine boiling water, gelatine, sugar, and orange rind.
Bring to a boil and let it sit for about 10 minutes off the heat.
Combine and set
In a bowl, have the strained orange and lemon juice ready.
Strain the mixture from the saucepan into the bowl with the juices.
When cool, pour into a mold rinsed with cold water.

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.
- Sugar
- Adds sweetness and balances the sharpness of the citrus juices.
- Orange juice
- Provides the main flavour and liquid base of the jelly.
- Lemon juice
- Adds acidity that brightens the flavour of the orange.
The step that matters
Straining the mixture into the juices. Straining removes the rind and any solids so the jelly sets clear and smooth. Gelatine must be fully dissolved in hot liquid first, or it will set unevenly and leave grainy specks.
