Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the sauce when browned with fat, giving body and a nutty flavour.
- Butter or dripping
- Fat that carries flavour and helps the flour brown into the roux.
- Beef or veal
- Adds meaty depth and savoury flavour to the stock.
- Tomato conserve
- Adds sweetness and acidity, rounding out the sauce's colour and flavour.
- Onion
- Browns and adds sweetness and aromatic depth to the stock.
- Stock
- Forms the liquid base that the roux thickens into a sauce.
The step that matters
Browning the flour mixture. Flour must be cooked slowly over low heat until evenly brown; stopping early leaves a raw starchy taste, while overheating scorches it and makes the sauce bitter.
Flavor stand-ins for the mace

Fit is the average pairing score against carrot, onion, beef, ham, parsley, celery, butter. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
