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 juice
Peel the oranges very thin and squeeze the juice over the rind, avoiding long exposure to prevent bitterness.
If the oranges are very sweet, add juice from a Seville orange or lemon.
Make the jelly
Dissolve the isinglass in a small quantity of water.
Melt the sugar and let the syrup and isinglass cool.
Mix the cooled syrup with the juice and strain into a mold.

Lemon and sugar 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
- Isinglass
- Sets the liquid into a firm, tender jelly as it cools.
- Loaf sugar
- Sweetens the jelly and adds body to the syrup.
- Oranges
- Provide the main flavour and most of the liquid for the jelly.
- Lemons
- Add acidity that brightens the flavour and balances sweetness.
The step that matters
Avoid long exposure of the peel to the juice. Leaving the juice in contact with the rind draws out bitter compounds from the peel, so the jelly can taste bitter. Squeezing quickly and straining keeps the flavour clean.
