Why it works: Lemon and orange 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
Simmer the isinglass in the water until dissolved.
Add the peels of the lemon and orange.
Once the isinglass is dissolved, add the lemon juice and orange juice.
Sweeten with white sugar, adjusting based on the season's fruit flavor.
If needed, add the peel of a Seville orange for extra flavor.

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.
- Orange juice
- Provides the main citrus flavor and liquid body of the jelly.
- White sugar
- Sweetens the jelly and balances the sharpness of the citrus juice.
- Lemon juice
- Adds acidity that brightens the flavor and sharpens the orange taste.
The step that matters
Dissolve the isinglass fully before adding the juice. Isinglass must be completely dissolved in the simmering water to set properly. Adding acidic juice before that is finished can leave it unevenly gelled, so the jelly may not set firm and clear.
