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

What each ingredient does

Calf's head
Provides gelatinous body and rich flavour once simmered until tender.
Flour
Thickens the stock when cooked in butter as a roux.
Butter
Carries the aromatics and forms the base of the roux, adding richness.
Cream
Adds richness and smooth body to the finished soup.

The step that matters

Making the roux. Flour must be stirred in hot butter until white and cooked smooth before the stock is added; undercooked roux tastes raw and floury and clumps when liquid is added.

Swap the onion
