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 ↓
Fruit Jelly
Ingredients
Directions
Make the jelly
Dissolve the gelatine by pouring cold water over it and letting it stand until swollen.
Pour 1 pint of boiling water over the gelatine, stirring until fully dissolved.
Add 1 pound of granulated sugar, the juice and grated rind of 3 lemons, and the juice of 3 oranges.
Strain the mixture.
Assemble and set
Divide 4 oranges into small sections.
Slice 6 bananas.
Place the fruit in a serving bowl.
When the jelly begins to congeal, pour it over the fruit.
Refrigerate until the jelly is fully set.

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, sliceable jelly as it cools.
- Granulated sugar
- Adds sweetness and helps balance the sharpness of the citrus juice.
- Lemons
- Provide acidity and aroma, with the grated rind adding fragrant oils.
- Oranges
- Add sweetness, juice for flavour and fresh fruit sections for texture.
- Bananas
- Add soft texture and sweetness to the fruit layer.
The step that matters
Pour the jelly when it begins to congeal. If the jelly is still fully liquid, the fruit will sink and float unevenly. If it has set too far, it will not blend with the fruit. Pouring at the thickening point suspends the fruit evenly.
Swap the banana
How well each one fits the dish's main ingredients (sugar, lemon, orange, grape):
- Figfits better
- Vanillafits better
- Cranberryfits better
- Bananathe original
Fit is the average pairing score against sugar, lemon, orange, grape. Candidates are from the same food group and used in at least 100 recipes.
