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

What each ingredient does

Mock turtle soup beans
Form the body of the soup, thickening into a smooth purée once rubbed through.
Beef broth
Provides the savory meaty base that carries the flavor of the soup.
Butter
Enriches the soup and, rolled in flour, thickens it as it simmers.
Lemons
Add acidity and bright aroma to balance the rich, heavy soup.

The step that matters

Stir in the butter rolled in flour. Flour-thickened butter must be whisked into a simmering liquid so the starch disperses and hydrates evenly; added to a cold or unstirred soup it clumps and leaves lumps.

Swap the lemon
