Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Onion: Frying until brown builds colour and savoury flavour in the sauce.
Butter: Adds fat and rich flavour for frying the onion.
Gelatine: Adds body and a slight setting texture to the liquid.
Liebig's extract of beef: Concentrated beef flavour that deepens the sauce's savouriness.
Brown thickening: Thickens the liquid so the sauce coats food.

The step that matters

Frying the onion until brown. Browning the onion through the Maillard reaction creates colour and deep savoury flavour that carry into the sauce. Pale onions give a flat, weak sauce, while burnt onions add bitterness that cannot be removed later.

Fit is the average pairing score against onion, butter, celery, beef. 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).
