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
Combine boiling water, gelatin, sugar, and orange rind in a saucepan.
Bring to a boil.
Remove from heat and let the mixture sit for about 10 minutes.
Combine and set
In a bowl, combine the strained orange juice and lemon juice.
Strain the contents of the saucepan into the bowl using muslin or a strainer.
Once cool, pour the mixture into a mould rinsed with cold water.

What each ingredient does
- Gelatine
- Sets the liquid into a firm, wobbly jelly as it cools.
- Loaf sugar
- Sweetens the jelly and balances the sharpness of the citrus juices.
- Orange juice
- Provides the main orange flavour and most of the liquid in the jelly.
- Lemon juice
- Adds acidity that brightens the flavour and sharpens the sweetness.
The step that matters
Straining the hot mixture into the juice. Gelatine only sets properly when it is fully dissolved and the liquid is clear. Straining removes rind and any undissolved bits, so the jelly sets smooth and clear. Pouring it in while still very hot could weaken the setting, so let it cool before moulding.
