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

What each ingredient does

Pickled cucumbers: Provide the main flavor and acidity of the sauce.
Butter: Adds richness and fat to the sauce.
Flour: Thickens the liquid as it heats, giving the sauce body.
Cream or brown gravy: Adds richness and smoothness to finish the sauce.
