Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Boiled Apple Pudding
Ingredients
Directions
Prepare
Make a suet crust using 1 lb of flour and other ingredients in proportion.
Butter a basin and line it with some of the crust.
Fill and wrap
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.
Flour a cloth, place it over the pudding, tie it securely, and put it in boiling water.
Boil and serve
Boil for 1.5 to 2.5 hours, depending on the size of the pudding.
Turn it out of the basin and serve immediately.

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.
- Suet crust
- Provides a rich, tender pastry that steams around the apples as they cook.
- Apples
- Supply the bulk of the filling and moisture that softens as the pudding boils.
- Sugar
- Adds sweetness to balance the tartness of the apples and lemon.
- Lemon juice
- Adds acidity that brightens the flavour of the apples.
The step that matters
Securing the cloth and boiling. The cloth must be floured and tied tightly so the crust holds its shape, and the pudding must stay fully submerged in boiling water. Steady boiling cooks the crust through and the fruit evenly over the full time.
Swap the apple
How well each one fits the dish's main ingredients (flour, butter, sugar, lemon):
- Raisinfits better
- Vanillafits better
- Figfits better
- Applethe original
Fit is the average pairing score against flour, butter, sugar, lemon. Candidates are from the same food group and used in at least 100 recipes.
