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 ↓

Butter and flour 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
- Pickled tongue
- Main protein; long boiling softens its tough muscle fibres until tender.
- Tomatoes
- Provide the sauce's acidity and body; reducing them concentrates flavour and thickens the liquid.
- Butter
- Adds richness and a smooth, glossy finish to the sauce.
- Flour
- Thickens the sauce as its starch swells when the mixture is heated.
The step that matters
Bring the sauce to a boil after adding the butter mixture. Flour only thickens fully once the sauce reaches a boil and its starch swells. Stopping early leaves the sauce thin and can leave a raw, floury taste.
Swap the tomato
How well each one fits the dish's main ingredients (butter, flour):
- Shallotfits better
- Leekfits better
- Arrowrootfits better
- Tomatothe original
Fit is the average pairing score against butter, flour. Candidates are from the same food group and used in at least 100 recipes.
