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

What each ingredient does

Mutton: Provides the main meat, which becomes tender when gently stewed in the sauce.
Shallots or onions: Add aromatic sweetness and body to the sauce as they soften with the butter.
Butter: Adds richness and carries the flavour of the aromatics when melted.
Flour: Thickens the sauce as it cooks with the butter and onions.
Veal broth or gravy: Forms the savoury liquid that becomes the body of the sauce.
Pickled cucumbers: Add sharp acidity that contrasts with the rich meat and sauce.

The step that matters

Sautéing the shallots or onions with flour. Cooking flour in butter over low heat builds a smooth roux that thickens the sauce. Heat that is too high can scorch the flour and leave a bitter taste, and cooking only until partly done leaves the onions raw-tasting.
