Why it works: Lemon and pistachio match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 431 recipes. Both carry alpha-pinene, which smells pine, turpentine. The science ↓
Apple Jelly
Ingredients
Directions
Prepare the fruit
Peel and core the apples, then cut them into small pieces.
In a saucepan, combine the apples, sugar, and water.
Grate the yellow rind of the lemon over the apples, avoiding the bitter white part.
Squeeze the lemon juice through a strainer onto the apples.
Boil the mixture until the apples are tender, stirring occasionally.
Make the jelly
Dissolve the gelatine in ½ cup of cold water by placing it near the fire.
Once the apples are a pulp, strain them through a sieve into a bowl.
Stir the melted gelatine into the apple puree until smooth.
If desired, color part of the apple with cochineal.
Mould and serve
Rinse a 1½ pint mold with boiling water, then cold water.
Decorate the bottom of the mold with chopped pistachios or preserved cherries.
Pour the apple mixture into the mold, layering colored and plain apple if using cochineal.
Set the mold aside in a cool place to firm up.
To serve, dip the mold in boiling water briefly and carefully turn out the jelly onto a dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Provide the pulp that sets into the body of the jelly and gives its flavour.
- Gelatine
- Sets the strained apple puree into a firm, sliceable jelly as it cools.
- Lump sugar
- Sweetens the apples and adds body to the finished jelly.
- Lemon
- Adds acidity and aroma from its rind and juice, brightening the apple flavour.
- Cochineal
- Colours part of the apple mixture to create a red layer.
The step that matters
Dissolve the gelatine fully before combining. Gelatine must be completely dissolved and evenly stirred into the warm puree; undissolved granules leave specks and weak patches, and it must not be boiled, as overheating reduces its setting strength.
Swap the apple
How well each one fits the dish's main ingredients (lemon, sugar, pistachio):
- Limefits better
- Orangefits better
- Avocadofits better
- Applethe original
Fit is the average pairing score against lemon, sugar, pistachio. Candidates are from the same food group and used in at least 100 recipes.
