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
Forms a roux with the butter that thickens the broth into a smooth sauce.
Beef broth
Provides the liquid and savory beef flavor that forms the body of the sauce.
Vinegar
Adds acidity that brightens the rich, savory sauce.
Pickled cucumbers or walnuts
Add tangy crunch and texture to the finished sauce.

The step that matters

Gradually add the beef broth, stirring constantly. Adding liquid slowly while stirring lets the flour disperse evenly in the butter, preventing lumps and giving a smooth, thickened sauce.

Swap the parsley
