Why it works: Anchovy and sauce are a kitchen classic. They rank in the top 2% of all ingredient pairs, and cooks put them together in 2,057 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- All-purpose flour
- Thickens the stock into a smooth gravy as its starch swells when heated.
- Dripping
- Carries the browning of the onion and adds rich flavour to the gravy.
- Onion
- Browns in the fat to add savoury, sweet flavour, then is strained out.
- Stock
- Forms the liquid base that the flour thickens into gravy.
The step that matters
Stir the flour mixture until it boils. Flour must be heated to boiling so its starch swells and thickens the liquid; stopping early leaves the gravy thin and tasting of raw flour.
Swap the nutmeg
How well each one fits the dish's main ingredients (onion, butter, flour, pepper, vinegar, anchovy, sauce):
- Capersfits better
- Garlicfits better
- Parsleyfits better
- Nutmegthe original
Fit is the average pairing score against onion, butter, flour, pepper, vinegar, anchovy, sauce. Candidates are from the same food group and used in at least 100 recipes.
