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.
