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
Grate the peel of the oranges and lemons into a bowl.
Squeeze the juice from the oranges and lemons into the bowl.
Make the jelly
Boil the sugar in the water until it reaches a hard boil.
Pour the boiling sugar mixture over the isinglass and stir until dissolved.
Add the juice mixture to the dissolved isinglass and strain through coarse muslin.
Let the mixture stand until it is half cold.
Mold and turn out
Pour gently into molds that have been wet with cold water.
Before turning out, place the molds in warm water and loosen the edges with a spoon.

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 jelly as it cools.
- Sugar
- Sweetens the jelly and adds body to the set.
- Oranges
- Provide the main juice, flavor, and aroma of the jelly.
- Lemons
- Add acidity that brightens the citrus flavor.
The step that matters
Pour the boiling sugar mixture over the isinglass and stir until dissolved. Isinglass is a gelatin-like protein that must fully dissolve in hot liquid to set evenly; undissolved bits leave weak spots and grainy texture in the finished jelly.
