Why it works: Apple and lemon 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 ↓
A Custard Apple Pudding
Ingredients
Directions
Make the apple base
Pare and quarter the apples.
In a saucepan, combine apples, lemon rind, water, and sugar; simmer and stir until reduced to jam.
Pour the jam into a bowl, remove the lemon peel, and stir in butter and lemon juice.
When cool, add the egg yolks and mix well.
Bake and finish
Bake in a buttered mold for 30 minutes.
Turn out, brush with egg white, cover with sifted sugar, and return to the oven for 5 minutes to harden the icing.
Serve hot or cold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Cooked down into jam, they form the body and flavor base of the pudding.
- Egg yolks
- Added when cool, they enrich the mixture and help it set when baked.
- Butter
- Adds fat for richness and a smooth, tender texture.
- Sugar
- Sweetens the jam and helps it reduce to a thick, spreadable consistency.
- Egg white
- Brushed on top, it helps the sugar coating set into a crisp glaze.
The step that matters
Adding the egg yolks when the jam is cool. Hot jam can scramble egg yolks, leaving lumps and a grainy texture. Letting the mixture cool first lets the yolks blend in smoothly and bake into an even set.
Swap the apple
How well each one fits the dish's main ingredients (lemon, sugar, butter, egg):
- Vanillafits better
- Orangefits better
- Raspberryfits better
- Applethe original
Fit is the average pairing score against lemon, sugar, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
