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 ↓

Flour and butter barely smell alike, yet cooks put them together in 124,287 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
- Stewed tomatoes
- Provide the main body, acidity and flavour of the sauce.
- Flour
- Thickens the tomato liquid into a smooth sauce when heated.
- Butter or cream
- Adds fat and richness, softening the sharpness of the tomatoes.
The step that matters
Blend the flour in cold water before adding it to the boiling tomatoes. Flour added dry or straight into hot liquid forms lumps that are hard to remove. Mixing it into cold water first disperses the starch so it thickens the sauce evenly when heated.
Swap the tomato
How well each one fits the dish's main ingredients (flour, butter):
- Shallotfits better
- Leekfits better
- Arrowrootfits better
- Tomatothe original
Fit is the average pairing score against flour, butter. Candidates are from the same food group and used in at least 100 recipes.
