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 ↓
Boiled Apple Pudding
Ingredients
Directions
Prepare
Prepare a suet crust using 1 lb of flour.
Butter a basin and line it with some of the crust.
Fill and seal
Pare, core, and slice the apples, then fill the basin with them.
Add sugar, lemon peel, and lemon juice to the apples.
Cover the filling with the remaining crust and pinch the edges together.
Boil and serve
Flour a cloth, place it over the pudding, tie it securely, and submerge in fast-boiling water.
Boil for 1.5 to 2.5 hours, depending on the size of the pudding.
Turn out of the basin and serve immediately.

Apple and sugar 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
- All-purpose flour
- Forms the structure of the suet crust that encloses the filling.
- Apples
- Provide the bulk of the filling and moisture as they soften during boiling.
- Lemon juice
- Adds acidity that brightens the sweetness of the apples.
- Sugar
- Sweetens the apple filling.
The step that matters
Boil in fast-boiling water. The cloth must be tied securely and the water kept at a fast boil so the pudding cooks through evenly. Water that drops in temperature or a loose cloth lets water in, which can make the crust soggy and slow the cooking.
Swap the apple
How well each one fits the dish's main ingredients (flour, sugar, lemon):
- Raisinfits better
- Vanillafits better
- Orangefits better
- Applethe original
Fit is the average pairing score against flour, sugar, lemon. Candidates are from the same food group and used in at least 100 recipes.
