Why it works: Lemon and apple are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 7,551 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Jellied Apples
Ingredients
Directions
Prepare the gelatine
Soak the gelatine in ½ cup of cold water for 30 minutes.
Cook the apples
Boil 1½ pints of water, lemon juice, and sugar rapidly for 5 minutes.
Add the peeled, quartered, and cored apples a few at a time, cooking until tender.
Drain the apples and place them in a mold wet with cold water.
Set and serve
Dissolve the gelatine in the hot liquid and pour it over the apples.
Set aside to chill and serve with whipped cream.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Sugar and apple barely smell alike, yet cooks put them together in 16,478 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
- Gelatine
- Sets the liquid into a firm, sliceable jelly around the apples.
- Apples
- Provide the fruit body and mild flavour that the jelly holds together.
- Sugar
- Sweetens the syrup and balances the tartness of the lemon.
- Lemon
- Adds acidity that brightens the sweet syrup and flavour of the apples.
The step that matters
Dissolve the gelatine in the hot liquid. Gelatine must dissolve fully in hot liquid, or it will not set evenly and may leave gritty or cloudy patches. Pouring the liquid while it is still warm, not boiling, helps it spread evenly over the apples before it begins to firm.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, apple):
- Pearfits better
- Vanillafits better
- Apricotfits better
- Lemonthe original
Fit is the average pairing score against sugar, apple. Candidates are from the same food group and used in at least 100 recipes.
