Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the sauce and helps the onion brown evenly in the oil.
- Oil
- Carries heat to the onion and flour and helps them brown.
- Onion
- Adds savoury flavour and sweetness as it browns.
- Brown stock
- Forms the liquid base that gives the sauce its body and flavour.
The step that matters
Browning the onion and flour. Cooking over low heat and stirring constantly prevents scorching, which would make the sauce bitter. Gradual browning builds rich colour and flavour, while stirring keeps the mixture smooth and evenly coloured.

Fit is the average pairing score against flour, ketchup, pepper, sauce. 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).
