Why it works: Butter and flour 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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Provide the main body of the pudding, softening during baking and adding fruity flavor.
- Sago
- Absorbs moisture as it cooks and forms a soft, starchy filling around the apples.
- Sugar
- Adds sweetness to the sauce and balances its flavor.
- Butter
- Adds fat and richness to the sauce, giving it a smoother mouthfeel.
- Flour
- Thickens the sauce as it heats, giving it body.
The step that matters
Boiling the sauce with flour. Flour must be heated fully in the liquid so its starch swells and thickens the sauce. Stirring while it comes to a boil helps prevent lumps and a raw, pasty taste.
Swap the apple
How well each one fits the dish's main ingredients (sugar, butter, flour):
- Raisinfits better
- Vanillafits better
- Figfits better
- Applethe original
Fit is the average pairing score against sugar, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
