Why it works: Pineapple and lemon are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 1,964 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Pine Apple Jelly
Ingredients
Directions
Prepare the pineapple base
Pound the pineapple and place it in a saucepan with water, lemon rind, lemon juice, and sugar.
Simmer for 30 minutes.
Add the gelatine and clarify
Dissolve the gelatin in a little water over low heat in a separate saucepan.
Once the pineapple mixture is cool, add the dissolved gelatin, whipped egg whites, and crushed shells.
Whisk the mixture over low heat until it comes to a boil.
Strain the mixture.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pineapple
- Provides the main fruit flavour and sweet-sharp body of the jelly.
- Leaf gelatine
- Sets the liquid into a firm, wobbly jelly when chilled.
- Eggs
- Whites and shells collect particles as they heat, clarifying the jelly to a clear finish.
- Loaf sugar
- Adds sweetness and helps give the jelly a smooth, clean set.
- Lemons
- Adds acidity that brightens the pineapple flavour and balances the sugar.
The step that matters
Adding the gelatine and egg whites to a cool mixture. If the pineapple mixture is still hot, the whipped egg whites can scramble and the gelatine may weaken. Letting it cool first protects the foam and the set.
Swap the pineapple
How well each one fits the dish's main ingredients (sugar, lemon, egg):

Fit is the average pairing score against sugar, lemon, egg. Candidates are from the same food group and used in at least 100 recipes.
