Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the sauce and carries flavor as the base of the roux.
- All-purpose flour
- Thickens the broth into a smooth sauce when cooked with the butter.
- Beef broth
- Forms the liquid body of the sauce and adds savory beef flavor.
- Vinegar
- Adds acidity that brightens the rich, savory sauce.
- Mushroom ketchup or port wine
- Adds deep savory and sweet notes to the sauce.
- Pickled cucumbers or walnuts
- Adds tangy or nutty bite that contrasts with the rich sauce.
The step that matters
Simmer until thickened to your liking. Flour must simmer long enough to swell and set fully, or the sauce stays thin and tastes floury. Simmering also reduces the liquid, concentrating flavor. Stop when it coats a spoon.
