Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lard
- Fat that carries the onion flavor and helps the flour cook evenly.
- Flour
- Thickens the sauce as its starch swells in the hot liquid.
- Beef broth
- Provides the liquid base and savory moisture for the sauce.
- Onion
- Frying it until yellowish builds sweet, savory aroma in the sauce.
- Sugar
- Adds sweetness that balances the savory broth and herb flavor.
- Tarragon
- Supplies the herbal, slightly anise-like aroma that defines the sauce.
The step that matters
Let the sauce boil until it is medium thick. Flour thickens only when its starch is heated enough in liquid to swell. Stopping early leaves the sauce thin, while boiling too long can make it gluey or reduce it too far.

Fit is the average pairing score against flour, beef, sugar, tarragon, cream. 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).
