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
Prepare
Prepare your fruit by chopping it if necessary.
In a bowl, combine the fruit with the lemon juice, orange juice, and sugar to taste.
Dissolve the gelatin in a little warm water or the juice from the canned fruit.
Mix the dissolved gelatin into the fruit mixture.
If desired, add a little wine or other liquor.
Set and serve
Pour the mixture into a square mold and refrigerate until set.
Once set, cut into squares and serve with poultry or meats.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatin
- Sets the liquid into a firm, sliceable jelly as it cools.
- Fruit
- Provides the main flavor, color, and body of the jelly.
- Lemon juice
- Adds acidity that brightens the sweetness of the fruit.
- Sugar
- Sweetens the mixture and balances the tartness of the citrus.
The step that matters
Dissolve the gelatin fully. Gelatin must be completely dissolved in warm liquid before mixing; undissolved granules leave soft spots or stiff clumps and can prevent an even set.
Swap the peach
How well each one fits the dish's main ingredients (lemon, orange, sugar, gelatin, wine):

- Peachthe original
Fit is the average pairing score against lemon, orange, sugar, gelatin, wine. Candidates are from the same food group and used in at least 100 recipes.
